[Python-Dev] Interop between datetime and mxDateTime

I haven't been following any of the datetime machinations closely, but this
issue of reading pickles caught my eye.  Why would the two versions have to
be able to instantiate each others' pickles?  That seems like an
unreasonable constraint to place on things.  Is there something
platform-dependent in datetimemodule.c that would mean it couldn't be built
everywhere?  I thought datetime.py was simply a place to try out new ideas
before moving them to C.
