this test was suggested by Dr Joel in the patch V1 so I just improved it in
this version
An I wasn't able to fully understand in the previous patch.
you can read more details for the test in this mail

So that when I join that pthread and the thread_id becomes invalid and
could be used for
testing the ESRCH exception
