--  This unit is not implemented in typical GNAT implementations that lie on

--  top of operating systems, because it is infeasible to implement in such

--  environments. The RM anticipates this situation (RM D.11(10)), and permits

--  an implementation to leave this unimplemented even if the Real-Time Systems

--  annex is fully supported.

--  If a target environment provides appropriate support for this package, then

--  the Unimplemented_Unit pragma should be removed from this spec, and an

--  appropriate body provided. The framework for such a body is included in the

--  distributed sources.
