Spawn has efficiency issues, and sets a hard limit on elapsed
time, it expects to run short-lived processes. Now it is true
that smtpd(8) connections to policy services live roughly as
long as smtpd(8) itself, which is rarely as long as the default
spawn command timeout, but there is here room for impedance
mismatches.
