While testing GIL changes I ran against an interesting bug in regrtest when run with -j<big number>. It turns out that we can't consume a generator from two threads simultaneously.


Exception in thread Thread-8:
Traceback (most recent call last):
  File "/home/antoine/py3k/gilprio/Lib/threading.py", line 521, in _bootstrap_inner
    self.run()
  File "/home/antoine/py3k/gilprio/Lib/threading.py", line 474, in run
    self._target(*self._args, **self._kwargs)
  File "/home/antoine/py3k/gilprio/Lib/test/regrtest.py", line 523, in work
    test, args_tuple = next(pending)
ValueError: generator already executing
