Well, knowing that they crash less in 3.3 doesn't really fix the problem now, does it?
We can consider two options then:
1) A multiprocessing specific fix. Removing this handle close gil release (which is superfluous, since these calls aren't blocking in any real sense) will certainly remove _this_ instance of the crash. An alternative is to make this worker thread non-daemon. That shouldn't be too hard and shouldn't have any other side effects.
2) A general daemon thread fix. For example, removing the GIL at the start of the shutdown process will make it impossible to release it. We can do this by setting interpreter_lock to NULL.
I don't see the point of having 2.7 in bug fix mode if we can't fix bugs.
