Let me guess--the server is running Windows, right? This kind of problem has
been reported before, and IIRC seems to have something to do with the remote
server leaving the file open before the rename occurs. Renaming open files
is verboten under Windows, so it errs out. Search the mailing list archives
and you'll find some more details; I believe the conclusion was that it was
a problem in the remote server and not libcurl, but don't quote me on that.
