Yes, but before you do... :-)

If it's not too late can you do:

	ps -o f -l

Or if anyone "succeeds" at wedging processes (especially if you
already have the above patch applied) can you try this?

I have a trivial procedure that produces unkillable processes
before the above patch, and this patch fixes that case.  I've got
one person reporting that he can still get wedged processes even
with the above patch though so I'm looking for a bit more information.

Thanks...
