urllib.py: '+' is not always safe (even though the RFC says so :-( )
whrandom.py: throw away top bits of time to avoid overflow on Mac
(where times can be negative)
constructors. There is no backward compatibility. Not everything has
been tested.
* aiff.{py,doc}: deleted in favor of aifc.py (which contains its docs as
comments)
* Fixed calendar.py, mimetools.py, whrandom.py to cope with time.time()
returning a floating point number. (And fix old bug in calendar)
* Add recursion level to mainloop.mainloop(), to make it reentrant.
