the stack does not get freed or reused even if the delay in creating threads is
increased to up to 10 seconds

Sorry for my mistake, because the thread created by pthread_create is joinable,
and when a terminated joinable thread has been joined are the last of its
resources  released  back  to the  system, so this is not a BUG.
