The issue really lies in your AV scanner first (as it's holding the
file locked for its exclusive use for too long) and SQLite second
(because you *might* argue that it should wait longer). It's not a
TortoiseSVN issue, it *might* be a Subversion library issue, it's
probably a SQL + Subversion issue. But the root issue is your AV
software. Make it behave properly.
