unkillable processes after debugging on 5.3R

[Marc Olzheim]

The scheduler is plain SCHED_4BSD btw.

lsof (ports/sysutils) doesn't display anything for pid 20328, but does
for 20326.
The output fstat -vp 20328 generates changes over time; when I try it
now, I get:

turtle:/#fstat -vp 20328

So it seems like some memory is reused but still accessible via the
'hanging' process...
