When someone asks if they should use POSIX shared memory, we generally tell them we prefer mmap'ed files, if you want a large path to things, and that has the bonus of not taking wired memory, providing the same string-based rendezvous, plus you can use FS permissions, including ACLs, to protect access to the shared memory itself.

Hmm. POSIX shared memory segments are wired down? That seems bad. Or is just a control block in the kernel?
