Re: [dwm] quitting dwm-in-pipe

My opinion is the pipe loop is not an ideal way to handle dwm status,
but it seems to be the only thing that works as it is coded. The problem
seems to be that the "while" command is actually the main X process when
dwm is run this way, so killing dwm does not end xinitrc. My choice would
have been to allow dwm to run as the final command in .xinitrc and also
allow it to read stdin...something like exec dwm < loop command, perhaps?

In any case, my current start script for dwm looks like this:

   while pidof dwm &>/dev/null
   do
      date +"[%H:%M] %a %b %d" && sleep 5
   done | /opt/dwm/bin/dwm

It's still not ideal for two reasons:
1) i still have to wait up to 5 seconds for X to shut down
2) sometimes it results in a broken pipe, presumably if dwm does not
   start immediately (pidof exits non-zero?).
