Modified Files:
	basesrc/etc: rc.subr

Log Message:
* provide wait_for_pids(), which spins until all the given pids don't exist
* run_rc_command():
	- add support for "poll", which by default, uses wait_for_pids() on
	  the list of matching processes
	- in the "restart" case, call "poll" between "stop" and "start"

this fixes the situation where certain services (e.g, amd, squid) would
take a bit longer to shutdown after receiving the kill signal to shutdown,
and "/etc/rc.d/foo restart" would fail in the `start' phase.
