I do them to get fresh updates, to commit to both brunches, and sometimes to
find the version in which a bug is introduced. Last month, because of
xulrunner and docs in trunk, my updates took ~8 hours.

By deleting all docs from trunk and moving xulrunner to a different
directory, the time of 21485 to 21862 updating has reduced to 0h29m (better
than 2x improvement).

I mean that long updates take approximately the same time on both systems.
Thus no, windows is not the problem.
