s/fixed/mostly worked around/ The problem is that the work around isn't perfect. The root cause is still not fixed. avg@ has some ideas on better ways to handle this, but it is a bit tricky to get this right since we also dont' want printfs to be delayed too much (and to fix this perfectly requires buffering printf output). -- John Baldwin _______________________________________________ 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"
