you should return whatever the tux() call returns. Normally tux() would
give you a value of 0 (TUX_RETURN_USERSPACE_REQUEST), but occasionally
it could return TUX_RETURN_SIGNAL (when a signal is caught) or
TUX_RETURN_EXIT (when Tux is being shut down). These are the only values
that are returned currently.

To debug this, could you log all tux() return values that are not 0? To
do this just start up the Tux daemon manually without the 'daemon'
prefix. The simplest way is to modify /etc/rc.d/init.d/tux and remove
the 'daemon' word. This means 'service tux start' will 'hang' after
startup but you'll get all printfs to that console. You can then abort
the daemon via Ctrl-C and 'service tux stop'.
