nobody's stopping you. ;)

I also would be quite interested in seeing a solution to this. I'm a bit
confused about your alternative to posix semaphores (I know you said
it wasn't satisfactory anyways, but I'm still curious). Are the bits used
like mutexes, where threads block on them until they're acquired? If
so, how did you avoid the race condition between freeing the semaphore
and blocking on the mutex?
And why do you need so many locks? I assume that characteristic 1) is
proposed in order to allow you to construct them on an as-needed basis.
Why can't you allocate a fixed set of semaphores and dynamically
associate them with resources as needed? (I believe Java does something
of the sort with monitors.) The overall limit on the number of semaphores,
and their initialization cost, don't seem to necessarily rule this out.
James, who wants the list to be a forum for experts who are not terribly
impatient with questions asked by those who,like himself, have less
experience ;)
