It's been a while; but I'm almost confident that according to my last reading of the POSIX man pages, the Linux implementation is actually perfectly correct -- the POSIX description is just very confusing... Note that this is a very old known issue, and there was previous discussion. (Which I'm too lazy to try digging up...) My conclusion was that trying to implement it correctly on top of the existing Mach interfaces would be tricky, for no real benefit -- we should just change the kernel interface instead to directly provide the semantics needed for POSIX behaviour. -antrik-
