Why are you checking out often? Check out the branch once. Work. When
done with the branch, when it has been merged and there's a new
branch you need to work on, "svn switch" the working copy you have to
the new branch. It will be quick, because the server will only have
to send you the difference between what you had and what you want.

By all means, keep the working copy and update it. Optionally, in
case you can't trust your "clean" script to clean up entirely (I
understand this happens often), write a script that runs "svn revert -
R /path/to/wc" to first discard any changes that may have been made,
then run "svn status" and parse the output and manually remove any
unversioned files that may have been left over. Then you can "svn
update" and then build again.
