Well, based on my observations, if the first pass doesn't reach the high watermark, then we are in a high pressure situation and so we would have to do some heavy-lifting anyways. In my opinion, it's better to start doing more work at once than trying to pretend that situation would somehow resolve itself. -- Andriy Gapon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
