Thanks, Michael.  I also got a reply at
http://answers.microsoft.com/en-us/windows/forum/windows_7-files/does-windows-7-do-file-caching-which-can-lead-to/181d8eca-4b59-4121-a8a9-545f465a9f61.
 That thread also provides a good reference to file virtualization:
http://support.microsoft.com/kb/927387 .

I achieved the desired effect of modifying the nonvirtualized _vimrc by clicking
on Compatibility Files to go to the virtualization directory and moving it from
there to the location ov the nonvirtualized _vimrc (thus overwriting it).
