If you're going to use it, make sure you use quotes:
	echo $! >"/var/run/xosvPid.$DISPLAY"
In normal circumstances (indeed, _all_ that I can think of) there
shouldn't be any weird chars in the DISPLAY variable, but this tiny
quoting fetish makes you safe from the more egragrious things.

Oh, and you probably want to remove /var/run/xosvPid.* at boot...
