ktrace output file not showing up in fstat

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I had a ktrace -i -f /tmp/something running, forgot that one of the 
sub-processes created was still running, rm'd /tmp/something and later 
wondered why /tmp was running out of space. I suspected an unlinked file, 
but didn't think of the ktrace output.

Why does that ktrace file not show up? Because it isn't associated with 
a process?
