It seems that Posix semaphores on Mac OS X have limitations, are not supported and not recommended. Probably their only use is to allow porting of linux programs. So the bug is that man pages for the sem_xxx() methods lack a statement saying that these functions are depracated and not recommended for new designs. Would anyone disagree with this? They aren't deprecated, we just don't promise that they are fully POSIX compliant at this time. This email sent to site_archiver(a)lists.apple.com
