Well, your commit here:;r2=1.156

gratiously provided to me by Peter Wemm solved the problem I had. I think we
are "talking past each other" with the lockup due to my bad choice of words:
The kernel did not deadlock, but a process executed after having multiple
tty's made that process hang with the ktrace I posted. The kernel itself
were still running fine though anything in need of /dev/tty would hang. I
hope this clears up the misconceptions.

The patch fixes my problem completely. Thanks!
