I believe that I've fixed *this* bug (sys/kern/kern_ktrace.c, rev
1.45).  The fix I made on Sunday (in 1.43) was incomplete.

I reproduced the hang you saw before.  With the fix mentioned above,
I've tested ktrace -c and ktrace -C and am no longer able to reproduce
it.

Sorry for the inconvenience.
