I believe it is mostly tradition, on Windows: We continue to do
things the way they have always been done.

On Linux, there is an additional rationale: small executables and
many files are cool, so we try to have as many shared libraries as
possible. (if you smell sarcasm - that is intentional)

I think that anything that would be reasonably replaced by third parties
(such as pyexpat.pyd) should be shared, and anything else should be part
of pythonxy.dll.
