Replying to myself.

I am using the syslog-ng from Debian Squeeze:
$ dpkg -l syslog-ng
And reloading the daemon is done via start-stop-daemon:
start-stop-daemon --stop --signal 1 --quiet --exec "$SYSLOGNG" \
which to me, there doesn't look to be anything that would cause the
extra program spawning in the above command.
Any ideas why reloading the daemon is causing extra programs to be "spawned"?
Thanks for the help!
