FWIW I noticed by accident that the latest stable version of a
not-competing database system has fixed a related bug:

http://bugs.mysql.com/bug.php?id=9709
(yes, it only took them two and a half years to fix it).

Note that their behavior on finding SHARING_VIOLATION or LOCK_VIOLATION
is to retry forever until the error goes away, on the theory that the
antivirus/backup software will soon release the file.
