	there's other reasons i dislike pidfiles.  they are not properly
	locked on creation, /var/run needs to be writable, no consideration
	to multiple daemons, no consistency guarantee between actual process
	table, and more.  if anything, a script that searches and kills
	"rtsold" would be much better.  or, we could extend kill(1) to take
	string as an argument and kill process under given name.
