/* If a fork, vfork or exec event was seen, then there are two
possible responses we can make:
1. If a catchpoint triggers for the event (ecs->random_signal == 0),
then we must stop now and issue a prompt. We will resume
the inferior when the user tells us to.
2. If no catchpoint triggers for the event (ecs->random_signal == 1),
then we must resume the inferior now and keep checking.
In either case, we must take appropriate steps to "follow" the
the fork/vfork/exec when the inferior is resumed. For example,
if follow-fork-mode is "child", then we must detach from the
parent inferior and follow the new child inferior.
In either case, setting pending_follow causes the next resume()
to take the appropriate following action. */
