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:

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.
