Damien George 368c1a0961 tests/thread/stress_schedule.py: Assign globals before running test. 
When threading is enabled without the GIL then there can be races between
the threads accessing the globals dict.  Avoid this issue by making sure
all globals variables are allocated before starting the threads.

Jim Mussared 8470cd0be9 py/scheduler: Add assert that scheduler is locked when unlocking. 
And add a test that shows how this can happen when multiple threads are
accessing the scheduler, which fails if atomic sections are not used.
