Re: [dwm] dwm-5.3

I have the same problem, although my status feed setup is nearly identical
to the one Neale shows. I use 'tail -f $XSTATUS | dwm' instead of 'dwm <
$XSTATUS' because for some reason dwm always showed EOF the other way.

Anyways, my .xinitrc is simply 'exec dwm-launch' and dwm-launch does the
fifo mess, starts the status script in bg, and starts up stalonetray and
nm-applet also in the background. No pid tracking or 'kill' commands.

When I quit with nothing but these running, X closes fine. but when I
quit with an xterm running, X blocks until I close the xterm. So, I
don't think this is the problem.
