when jackd was not started by qjackctl, then showing the "Active" status
indication as opposed to the "Started" one, you can perfectly leave it
without terminating jackd. however, please take care to check if your
post-shutdown script (Setup.../Options/Scripting) is not the once
suggested default, `killall jackd`, in which case it will do the "wrong"
thing ;)

yes, well, one could hack and port the Qt4 class implementation and get
rid of the implied kill() on QProcess::dtor(), something i've pondered a
long time ago, but never materialized ... the uber-procrastinator always
strikes whenever you expect it to, again and over again :)

probably not, from yours trully ;)
