Yes, this is definitely a host bug, which was reported to the appropriate 
people and fixed...

I had read the Changelog from -rc3 to final (after hearing from Christopher 
Aker that in -bk it had been fixed), and I seemed had a quick shoot about 
this... it was a fix from Roland McGrath about something strange, which made 
me guess it was the fix...

Roland McGrath:

  o fix bogus ECHILD return from wait* with zombie group leader

I'm not sure this is the fix, but it is possible indeed, given that the 
problem UML triggered was, IIRC, that when it exited, there wasn't a proper 
cleanup of the status, and the process became invisible but still kept a 
reference to the file in /tmp, preventing it from being deleted...

The changelog does not mention our particular bug it but there is a good 
reason for not mentioning it, and it's related to TASK_TRACED which is *the* 
problem in 2.6.9 with UML.

I think you can search for it on linux.bkbits.net... I'll do that when I have 
time...

However, I've received (after 2.6.10) the answer from Roland McGrath (ptrace 
coder / maintainer) about this problem, and he sent two more patches for 
this, which I'll bundle in next SKAS as a temp. solution and forward to 
you... I'll check if it is a complete solution.
