sem_acquire() function has this behavior:
After processing a request, any semaphores acquired by the process but not explicitly released will
be released automatically and a warning will be generated.
This is not a great thing, infact in this way the readers/writers classical IPC problem, with
writers precedence is impossible to implement !!!
I think an option to disable autorelease is usefull.
