Just to be clear.  It's not that something is changing the ACLs on the
file or anything.  Rather, a file or directory that is in use by another
program cannot be removed or relocated on Windows without some ugly
trickery.  This is a limitation of Windows itself.

I know that Cygwin implements some of the hacks to make it at least
appear possible to move and delete in-use files.  You could try running
your scripts with Cygwin's Ruby package to see if that helps things, but
be aware that the performance as a whole will likely suffer a bit.
