Just to let everyone know.  Eric Norum and I have worked on the binary
semaphore code over the past few months as part of his porting EPICS
to RTEMS.  We added a simple binary semaphore that is supposed to 
match the semantics of one of the VxWorks mutex types.  I have no
documentation but Eric N can comment.

If you find semantic differences that cause problems on OS objects
please let me know.  Sometimes these are not that bad to address.
