- * There are very likely to be lock-related bugs stemming from when the
-   kevent_copyin() and kevent_copyout() functions stopped holding the
-   kqueue lock. It would be nice to have a lock testing mechanism to 
-   check that the correct locks are held.. something like:
-
-      #define MTX_LOCKED 1
-      #define MTX_UNLOCKED 0
-      #if NDEBUG
-      #define LOCK_MONITOR(x)  int x
-      #define lock_assert(x,y) assert((x) == (y))
-      #define lock_acquire(x,y) do { pthread_mutex_lock((x)); y = MTX_LOCKED } while (0)
-      #define lock_release(x,y) do { pthread_mutex_unlock((x)); y = MTX_UNLOCKED } while (0)
-      #else
-      #define LOCK_MONITOR(x)  /**/
-      #define lock_assert(x,y) do {} while (0)
-      #define lock_acquire(x,y) do { pthread_mutex_lock((x)); } while (0)
-      #define lock_release(x,y) do { pthread_mutex_unlock((x)); } while (0)
-      #endif
-
-      struct foo {
-         LOCK_MONITOR(foo_lockstat);
-      }
-      ...
-
-      lock_assert(&kn->kn_lockmon, MTX_LOCKED);
-      lock_assert(&kn->kn_lockmon, MTX_UNLOCKED);

- * Add a counter that increments on each each kevent() call. When printing
-   debug information within kevent(), display the value of the counter.
-   This will be helpful when debugging a multithreaded program that may have
-   multiple kevent() calls executing in parallel.
 
  * Add a dbg_printf() statement within kevent_wait() to report the value
    of the timeout.
