In my experience of HP-UX and linux, they do differ. How much, I don't remember. I have a stupid proposal. Keep file lock aside. I think shared memory can be kept alive even after process dies. Why not write a shared memory segment id to a file and let postmaster check that segment. That would be much easier. Besides file locking is implemented using setgid bit on most unices. And everybody is free to do what he/she thinks right with it. May be stupid but just a thought..
