I will also test retrying MoveFileEx. As for MS developer support, they
are pretty good if you can give them a small reproduction test program
or recipe...that's what I was originally trying to do but couldn't
outside of Subversion. I'm not sure how they would respond to
Subversion and stress.pl as the recipe...they might look at it, but I'm
not sure. Even if they did and found a problem, though, it could easily
be months or years or never before they actually fix it.

That could be OK as a test but as a long term solution it looks a bit
dodgy--what happens if the MoveFile fails, or if the process is killed
between Delete and MoveFile, does the destination disappear?
Subversion relies on an Atomic rename, if you delete the destination
and then fail to complete the rename the working copy is likely to be
broken. I wonder if simply trying MoveFileEx again would do the

Has anyone asked Microsoft about this? I've been told their developer
support is pretty good, although I have never used it myself.
