Ah, yes.  You are correct of course.  My test setup (multiple full branches
of a trunk, all within the same shared local repo) is a bit unrealistic.
More likely, each of our developers would choose to keep one branch
(treeless or not) in sync with a central (remote) branch and create multiple
lightweight checkouts of the local branch.  As you point out, that still
does not address the need for a first full branch, but it is much better
than my artificial test situation.

I just did an experiment.  On the command line, I did three more iterations
of  "bzr branch <from_location> <to_location>" with both locations in the
same shared repo on a local disk.  During these operations, I aggressively
navigated through the limbo folders, watching them get created, populated
and ultimately deleted.  Every iteration completed with no errors and no
warnings.  In fact, when the folders were deleted, my Windows Explorer
window abruptly evaporated -- that is standard behavior on Windows.  Note
that I did not have any DOS or Cygwin shells open under the .bzr directory
in any of my experiments; that could be a different story which I do not
want to read today.

So unless I see this again, I will regard it as a fluke.  But if it does
happen again, I will probably send a jittery email begging for advice.  :)

Thanks
