Ion,
I was wondering whats your take on this. Is it something that can/should be added to boost or would you prefer that I just hack it in my code only?

My opinion is that there is no solution without kernel help. The original Interproces library (Shmem) emulated windows behaviour in Unix and it was a nightmare to get consistent behaviour. This was changed in Interprocess. The relationship between System V and POSIX resources is quite obscure and I don't see a proper way to solve this. The same problem with files and I haven't seen any clue to make Unix and Windows behavior identical until today: http://mg.to/2004/09/30/file_share_delete-in-shell-extension According to this, adding FILE_SHARE_DELETE to the shared memory emulation functions would allow, UNIX-like behavior for Windows files. I haven't had time to test this. This would not solve your problem, because you want Windows behavior (failure when the resource is in use) in UNIX. Regards, Ion
