New submission from Christian Heimes: Starting with Python 3.3 the select module access the uninitialized tv.tv_usec member of a timeval struct. I don't see the point of initializing the local variable long tv_usec from tv.tv_usec. The comment above the code states that long tv_usec is required as a workaround for Mac OS X.
