No, the MrsP (and maybe later the Migratory Priority Inheritance) semaphores 
are completely separate.

In theory it is possible to use it also for the uni-processor semaphores, but I 
am not sure if its worth to add this overhead.  The implementation with the 
resource count is analytically not correct, but very efficient.  Was this 
really a source for trouble in the last 20 years or so?
