        This worked excellently for me! I patched the kernel and rebuilt, then
tested aviplay... success. Then I cvsup'ed, built/installed world and
kernel, and started stress testing. I'm currently running two builds of X
4, one over NFS and one local, 'make cleandir' in /usr/src, AND avifile
(ok, it's a little choppy, but still runs). I'd say it's probably safe to
go back in the water again. Next stop, re-enabling softupdates. :)

        BTW, I'm probably wrong about this but looking at the patch it seems odd
to me that one of these is ifndef and the other is ifdef:

Just curious,

    I need someone really bad. Are you really bad?
