This is what Subversion already does. Windows virus scanners are
notoriously flaky, buggy and broken; we've had Windows-specific retry
logic in the code almost from day one because of that, and the back-off
and retry can be longer than one second. The fault is squarely at the
door of virus scanner developers; they're supposed to be invisible to
the user but the majority do not preserve filesystem semantics.

This would be a great way to randomly break working copies. The on-disk
state and the database contents have to be in sync; we go to a lot of
trouble to make sure they are. Decoupling database changes from
filesystem changes would pretty much guarantee that /any/ problem,
transient or otherwise, with the disk or filesystem would leave the
working copy irretrievably broken.
