fast revert+update for a continuous integration process?

Hello all, just a quick question:

We have a cruise control machine, and often want to grab the latest copy of
code. Naturally, we'd prefer to not pull down the entire tree when we have
the prior version sitting there already.

We can't use 'svn update' on our build machine, because it leaves
non-versioned files (build artifacts), and chokes on case changes in
windows. In essence it doesn't reliably leave us in a clean and pure state
for the next test run.

Something like a "revert to head" command, that also deletes non-versioned
files would be perfect - this would speed up a lot of people's cruise
control builds for sure.

Ideas?
