I did some more looking, and found that "tee" is used to redirect
logging to stdout as well as the Howto.list file.  So, I naturally tried
to run it in parallel without the listing.  Unfortunately, the cook
ended early (instead of hanging).  Note that in this case, none of the
final targets were even attempted (though sometimes some subset of the
final targets are created).  Apparantly, it is trying to wait, but no
processes have been spawned (though there are 4 threads of execution
which are terminated when wait() fails.
