OH.  MY.  GOD.

If I understand the problem and solution (which I marginally do), and Win9x vs.
WinNT/XP (which nobody really does), this ***~2.66x*** speedup should be even
greater on NT/XP.

I'm giddy with anticipation over what this might do to configure times etc.

This may be the coolest thing since sliced time.
