Its Cygwin/NTFS.  lstat() is slow.  readdir() is slow.  I have the
same problem on my Cygwin systems.

Yes, basically.  The Cygwin/NTFS issues Alex is pointing out are
exactly why git-gui has a "Trust File Modification Timestamp" option
on both a per-repository and global level.  My larger repositories
(~10k files) are difficult to work with without that option enabled.
