New submission from Antoine Pitrou <pit...@free.fr>:
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
