Subject: [PATCH] dwm: Sleep before attempting to reconnect to dwm

Sleep before trying to reconnect to the dwm socket after a detected
disconnection. If dwm is restarted in place, in most cases the reconnect will
fail before dwm gets a change to re-setup itself and the socket. A 1-second
delay can provide enough time for dwm to reinitalize itself before polybar
attempts to reconnect. As a result, the module can recovoer instead of the
entire application just quitting.
