That should work fine.  Parallel checkouts should not be a
problem... as long as they are not to the same destination.

This is pathological.  I wouldn't consider it an svk limitation.
The problem is that you've got two processes trying to write to
the same paths at the same time.  If you serialized those two
checkouts you'd see svk report something to the effect of "no
work to do" on the second checkout.  But since in your case both
are midstream, there is a race condition to check existence of
and write the same files.

Why would this situation ever arise in practical usage?
