Re: fc6 frysk-core failures.

Chris,

This is good progress and the thing to be looking at.  Unfortunatly, it 
may, or may not be the source of the problems, hard to say right now.

Broadly what is happening is that the test as successfully run (true?  
was there an earlier message reporting fail?) and now the tearDown code 
is going through and trying to destroy (using very brute force) any 
processes created during the test's run.  The brute force process, put 
simply, throws everything and anything repeatedly at the processes -- 
kill -9, kill -cont, detach, ... -- in the hope it can be made to go 
away.  A failure here could be due to kernel differences, but could just 
as easily be a timing issue.

In the log, going backwards from:

testManyExistingThreadAttached(frysk.proc.TestProcTasksObserver)
   >>>>>>>>>>>>>>>> start tearDown

what are the last few interactions involving pid 14860?  In particular 
is there anything indicating the state of that pid/tid's object.
