Waiting a while for NSD to finish shutting down is not a problem. For
example, when I shut down BIND, it usually takes 15-20 seconds for the
process to exit while it flushes journals and zones to disk. Similarly,
when I shut down Knot, it takes it several seconds to do its
housekeeping and free up allocated memory. So when my shutdown call
returns, I can be certain that the software has been fully shut down,
and there are no surprises.

You're welcome :)
