Ah, true.  But under the original arrangement, cat is unsupervised; it
could be killed, and we'd have the same problem, with even greater
likelihood, since cat wouldn't be automatically restarted.  Making one
cat/multilog service and another daemon-with-no-logger service (with
cat and the daemon connected by the fifo) would take care of
automatically restarting cat, but we'd still have the same problem
with a small window.  Best to fix the daemon, of course, preferably
with the maintainer's cooperation.
