I committed a change in trunk revision 110520 which should make this
part faster, as these functions now avoid calling 'stat' as much as
possible. When the binaries of the next development snapshot appear
on http://alpha.gnu.org/gnu/emacs/windows/, or if you can build Emacs
yourself, please try that and see if things are better now when the
Netlogon service is running.

I'd still like to see this information, to make sure there isn't any
other place that slows down the startup.
Thanks.
