I'm trying to implement a low-overhead shared (read) lock using
signal semaphores, and I've come up with a way that will work
if several tasks can effectively share ownership of a semaphore.
So, my question is: 

What happens if a task ReleaseSemaphore()'s a semaphore which another
task had previously ObtainSemaphore()'d?  The semaphore structure
has a field for the owner of the semaphore; would changing this field 
prior to the release be necessary or desirable? 

Thanks in advance,
