Profile of hg clone on windows

[Daniel Santa Cruz]

This was ran on a Windows XP box using and IDE drive with NTFS.

I have included:
* Size of the project (find)
* hg clone timmings
* hg clone -U timming
* hg clone --profile output

This runs quite a bit slow, as you can see.  I am running python.org's
python, and have used the module found in sourceforge for python that
gives hardlinking capabilities.  Notice how under cygwin, even the
find runs slow.

Daniel.
