[issue10824] urandom should not block

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

This would change semantics of the library call, though.
I see two possible solutions:
- do nothing and let users tackle the issue if necessary (e.g. by calling open() themselves and using select() on the resulting fd)
- add an optional "blocking" parameter to os.urandom() that, if False, would return None when no data is available
