Hmm, a little more digging shows that it's hanging on reading the
output of /bin/upas/send in data() in smtpd.c.  I worked around that by
only reading send's stderr output if status is non-zero.  Moving
beyond that, it seems to hang forever in proc_wait(), which is sort
of strange.  That would be, I think, waiting for send's exit status.
This is a bit complex for me as I'm debugging this over SSH using
ed, so the more productivly enhancing tools are unavailable at the
moment.
