Hi Anthony,

For all cases mentioned above I would expect the shutdown hook to get
invoked. If a thread (main or otherwise) exits for any reason (due to
"return" or exit()) I would want the shutdown hook to get invoked so I can
do the proper cleanup. Do you foresee any problem with this behavior?

Thanks,
Gili
