    Yah.  I also think it uncovered some VM bugs.  Since resident causes
    the kernel to basically do the equivalent of a fork off the registered
    vmspace every time you exec a resident'd program, the result is that
    the system is doing a lot more fork-like behavior then it would normally.
    Usually only services like sendmail fork.  This exercises the more
    obscure features of the VM system a lot more, and I am getting
    occassional user process faults in my buildworld tests when I
    make /usr/bin/* resident.

    I'm tracking it down.
