Non-portable *how*? What exactly would happen?
I think this is (always has been) a considerable blind spot on the part
of BSD partisans. Sure, we're happy to gripe about persistent SysV IPC
objects every time we have to remember how to use ipcrm, but bound AF_UNIX
sockets have the same issue, and we just ignore it.
