Win32 does not think the idea of multiple threads sharing a lock is a far
fetched idea.  It provides a series of locking and syncronizing primitives,
the variable count semaphore being one of them.

The iSeries could improve on this even further by providing permanent,
library resident, variable count semaphore objects.
