This version provides implementations of various locking primitives:

   - Plain events which can be signaled, reset and awaited for;
   - Arrays of events which can be signaled, reset and awaited in any
combination of in race condition free way;
   - Arrays of reentrant mutexes, deadlock-free with an enforced order of
locking;
   - Race condition free event distributing pulsed value to multiple tasks;
   - Reentrant mutexes;
   - Race condition free pulse events.

The documentation provides a discussion of using protected objects in Ada.
It represents a programming pattern for using entry parameter values in the
barrier and shows a way of avoiding race conditions. It also includes

   - A solution of the problem of tasks synchronization at a check point
based on sets of events;
   - A solution of the dining philosophers problem based on sets of
mutexes.
