Yes.  Because if you let the tool do the bootstrapping, it guaruntees that
the timestamps are ok. Otherwise, CruiseControl will think you have time t,
and you'll be dealing with time t+3 in your working copy because SVN is so
slow to update.

That's exactly right.

No.  I don't believe that your build tool should need to mess about with
the Version Control system.  And if it doesn't, the CI tool can make
reasonable assumptions about it's checkout.

It's as you describe.  poll -> detect change -> build -> poll.  Changes
that happen during the build will be collected in the next subsequent
build. If not, you're doing something wrong.
