        You can't block the first guess in LYUtils.c.  Your 'z'ap will be
detected when that gethostbyname() call times out, and similarly for any
subsequent guesses.  If the gethostbyname() call succeeds, the 'z'ap will
be detected in HTTCP.c, and that was changed to re-issue an un-'z'appable
gethostbyname() call if some ill-understood foul up occurs in the child of
the 'z'appable fork.  Perhaps some funny interaction is occurring due
to that change, but it seemed to all work OK when I tried it on Scott's
SPARC and an osf guest account I got recently.
