You're bumping into a common limitation of Windows, sadly.  It takes
some special tricks to fake deleting a file which is in use on Windows,
and I'm not certain that FileUtils has been written to perform such
tricks.  Note that I did say "fake deleting" since the file is not
really deleted until it is no longer in use.  It's just cleverly moved
and hidden from what I understand.

Cygwin and the Cygwin build of Ruby should be able to do this for you,
but you are doing something which is not normal for Windows.  Why do you
want to delete this temporary file while Mongrel is running in the first
place?
