Now we got to the per-workingtree tests, etc.

The main causes seem to break down into:
  bzrdir.clone() is known to be broken wrt locking, this effects
  everything that tries to 'push'

  shelf code is not compatible with strict locking

  merge code seems to have an issue. This might actually be the
  root cause of the clone() problems.
