[cups.general] Orphaned socket/lp's and lpstat's

[Michael Sweet]

We haven't had any new reports of zombies in a long time now; find out how cupsd was restarted - SIGHUP or SIGTERM should be find, SIGKILL will prevent cupsd from cleaning up after itself.

Anyone know if this is patched in any other versions or is this a bug as I would think the daemon should either keep track of it's children or the children should "call home" occasionally to make sure they aren't orphans.
