Turns out msysgit's remote-hg is not exporting the whole repository,
that's why it's faster =/

It seems the reason is that it would only export to the point where
the branch is checked out. After updating the to the tip I noticed
there was a performance difference.

I investigated and found two reasons:

1) msysgit's version doesn't export files twice, I've now implemented the same
2) msysgit's version uses a very simple algorithm to find out file changes

This second point causes msysgit to miss some file changes. Using the
same algorithm I get the same performance, but the output is not
correct.

Do you have a test case that demonstrates this? It would be helpful for
reviewers, but also helpful to msysgit people if they want to fix their
implementation.
