Description:
------------
Historically sem_acquire blocks the caller until the semaphore is acquired. The new option will allow the function to return immediately in case the semaphore is not available.

Bug #39168 suggests adding a timeout, but the underlying semop() function doesn't allow that. Some OSes (Linux, Solaris) have semtimedop(), but given it's not universally supported, I left it out.
