Since you're one of the few running NFS, you should also debug the
situation further. Apparently the Cygwin rename function fails, but
from your one-liner strace snippet there's no hint at all what happens.
The error should have been mentioned a couple of lines before. You
should also mention if you use a release version of Cygwin or a
developer snapshot. You know http://cygwin.com/problems.html, don't
you?
