*
* The application can modify the state of the activity by calling
* xpc_activity_set_state() with one of the following:
* - XPC_ACTIVITY_STATE_DEFER
* - XPC_ACTIVITY_STATE_CONTINUE
* - XPC_ACTIVITY_STATE_DONE
*
* @constant XPC_ACTIVITY_STATE_CHECK_IN
* An activity in this state has just completed a checkin with the system after
* XPC_ACTIVITY_CHECK_IN was provided as the criteria dictionary to
* xpc_activity_register. The state gives the application an opportunity to
* inspect and modify the activity's criteria.
*
* @constant XPC_ACTIVITY_STATE_WAIT
* An activity in this state is waiting for an opportunity to run. This value
* is never returned within the activity's handler block, as the block is
* invoked in response to XPC_ACTIVITY_STATE_CHECK_IN or XPC_ACTIVITY_STATE_RUN.
*
* Note:
* A launchd job may idle exit while an activity is in the wait state and be
* relaunched in response to the activity becoming runnable. The launchd job
* simply needs to re-register for the activity on its next launch by passing
* XPC_ACTIVITY_STATE_CHECK_IN to xpc_activity_register().
*
* @constant XPC_ACTIVITY_STATE_RUN
* An activity in this state is eligible to run based on its criteria.
*
* @constant XPC_ACTIVITY_STATE_DEFER
* An application may pass this value to xpc_activity_set_state() to indicate
* that the activity should be deferred (placed back into the WAIT state) until
* a time when its criteria are met again. Deferring an activity does not reset
* any of its time-based criteria (in other words, it will remain past due).
*
* IMPORTANT:
* This should be done in response to observing xpc_activity_should_defer().
* It should not be done unilaterally. If you determine that conditions are bad
* to do your activity's work for reasons you can't express in a criteria
* dictionary, you should set the activity's state to XPC_ACTIVITY_STATE_DONE.
*
*
* @constant XPC_ACTIVITY_STATE_CONTINUE
* An application may pass this value to xpc_activity_set_state() to indicate
* that the activity will continue its operation beyond the return of its
* handler block. This can be used to extend an activity to include asynchronous
* operations. The activity's handler block will not be invoked again until the
* state has been updated to either XPC_ACTIVITY_STATE_DEFER or, in the case
* of repeating activity, XPC_ACTIVITY_STATE_DONE.
*
* @constant XPC_ACTIVITY_STATE_DONE
* An application may pass this value to xpc_activity_set_state() to indicate
* that the activity has completed. For non-repeating activity, the resources
* associated with the activity will be automatically released upon return from
* the handler block. For repeating activity, timers present in the activity's
* criteria will be reset.

* The event handler's execution should be treated as a barrier to all

*
* Connections received by listeners are equivalent to those returned by

*
* If a barrier is issued after sending a message which expects a reply, the
* behavior is the same as described above. The receipt of a reply message will
* not influence when the barrier runs.
*
* A barrier block can be useful for throttling resource consumption on the
* connected side of a connection. For example, if your connection sends many
* large messages, you can use a barrier to limit the number of messages that
* are inflight at any given time. This can be particularly useful for messages
* that contain kernel resources (like file descriptors) which have a system-
* wide limit.
*
* If a barrier is issued on a canceled connection, it will be invoked
* immediately. If a connection has been canceled and still has outstanding
* barriers, those barriers will be invoked as part of the connection's
* unwinding process.
*
* It is important to note that a barrier block's execution order is not
* guaranteed with respect to other blocks that have been scheduled on the
* target queue of the connection. Or said differently,
