-------------------------------------

David,

2 notes:

1- I am testing the patch against my test cases and I still get a hang. One of 
my new test cases add a non daemon Timer to the MainWIthThreads.main() (test 
project 7).  In the case the Timer is not daemon, the code path that takes:     
void joinNonDaemonThreads()   will still hang. It looks like we still need a 
time out even with non daemon threads.

2- And as I said before, I personnaly would prefer an implementation that 
allows to use a time out and ignore the threads that have been interrupted but 
didn't properly quit. Did you intend the implementation to work like that, e.g. 
if one uses a non zero time out and do not choose to use stop() ?
