I'm not sure I'm going to help here, but the reason that
this happens is that certain services -- and the Desktop
Search tools are notorious for this -- get file handles with
FILE_SHARE_DELETE, which means that the file isn't actually
removed when it's deleted; only when the last of those handles
closes.

I did see a suggestion somewhere that, to circumvent this issue,
instead of removing it a file you need to move it to %TEMP%
(or wherever) and delete it there. I'll try to knock up a test
case to see if this works.
