What if your Apache isn't threaded (i.e. FreeBSD)?

Actually, this is not always the case...

If you are using speedycgi, or mod_perl, to speed up the running of routers2
under unix (and it makes a *big* difference on large installations), then it
will cache the .cfg definitions in memory for the duration of the perl
thread.  This means that, every time you change the .cfg files, you need to
either wait for the threads to expire (a few hours?) or touch the
routers2.cgi file (to force a thread reload).

If you don't use mod_perl or speedycgi, then you are quite correct -- there
is nothing to stop and restart and it is indeed impossible and pointless.
