If it hangs for longer than the busy timeout (the "-b" option
to the multiplexor), then the multiplexor unceremoniously kills the
Perl slave and tempfails the mail.

Really, this should be re-implemented using Net::DNS, and we need a way
to run DNS queries in parallel and collect the results as they come in.
This is on the TODO list.
