For this job there is alway's a good reason to add to system, this
is memory
management, simple application have no sure way to lock a memory
bloc if a
software allocate a memory bloc and crash there is no way to forbid
destruction by the system, even Mint SHM not lock memory (I don't
remember
if Mint share the memory or do a copy, I think it share it).
Are you sure? I had the impression that a shared memory block exists
as long as atleast one process has an open handle on it. So if two
apps (or a shared lib and an app) shares a memory block and one of
them crashes, the memory block will not be freed.
