It seems that any threaded implementation can just use thread-local
storage of one for or another for its per-running-operation needs.
Thus I think the interface as specified is sufficiently powerful.
This is assuming that the same THREAD will only run one SVN operation
at a time, which seems reasonable.

The logical extension if you wanted more expressive power is for SVN
to use thread-local storage to store the user context, but that seems
rather more effort than it's worth.
