DESCRIPTION
This module contains the entry points for the tasks used by the standard
libraries test application.

Each test task entry point invokes a test routine that returns a success/failure
indication, then gives a corresponding semaphore. An additional task monitors
these semaphores until it detects a failure or the completion of all test tasks,
then announces the result of the test.

NOTE: At present only a single test task is used, but more tasks may be added
in the future to enhance test coverage.
