In that case, you should be able to simply destroy the process and free whatever swap it has been allocated without ever giving it control. So is the issue that we don't want to send SIGKILL too aggressively, and send some other signal to give the process a chance to exit gracefully? -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
