BTW, as long as we're annoying the freebsd-stable list with discussions of workarounds, I'm wondering whether our shared memory code might have similar risks. Does FBSD 6 also lie about the existence of other-jail processes connected to a shared memory segment --- ie, in shmctl(IPC_STAT)'s result, does shm_nattch count only processes in our own jail?
People are, of course, welcome to read the Jail documentation in order to read the warning about not enabling the System V IPC support in Jails, and what the possible results of doing so are.
