timestamp check does not allow long

[nonnib]

if not (timestamp is None or isinstance(timestamp, int)):
    raise TypeError("'timestamp' must be an integer or None")

This causes issues for me in Python 2.7.3 on Windows because this is long:

timestamp=1369168852994

Suggested fix:

if not (timestamp is None or isinstance(timestamp, (int, long))):
    raise TypeError("'timestamp' must be an integer or None")

Confirming, I'm working on a fix.

Thanks for the report. The fix will be in the upcoming 0.5 release.
