I've run into lots of trouble with 3rd party programs opening any files
that change on the system and locking them down. For example, real-time
virus scanners, indexing software, and some builtin Win32 service that I
haven't pinpointed yet (it runs under a generic svchost.exe on XP).
These extremely annoying programs do not play nice and use
FILE_SHARE_DELETE, at least not in my experience.

There are large threads about this problem on the Subversion mailing
list (search for 'access denied') and some mentions of it on the CVSNT
mailing list, I believe.

Subversion ended up with a looping hack for Win32, at least until
something better is found.
