------------------------------+--------------------
 The transient event predates the self-contained binary semaphores
 available now via <rtems/threads.h> and is used as workaround to avoid
 explicit synchronization objects. There are two issues with the transient
 event.

 1. It is a per-thread resources and using it for different components
 makes debugging/development difficult. Issues noticed in one component my
 be caused by another component.

 2. The diagnostic information (e.g. "task" shell command) is poor.

 Replace the transient event with a binary semaphore if possible.
