message:
  All WorkingTree methods which write to the tree, but not to the branch
  have been converted to use ``needs_tree_write_lock`` rather than 
  ``needs_write_lock``. Also converted is the revert, conflicts and tree
  transform modules. This provides a modest performance improvement on 
  metadir style trees, due to the reduce lock-acquisition, and a more
  significant performance improvement on lightweight checkouts from 
  remote branches, where trivial operations used to pay a significant 
  penalty. It also provides the basis for allowing readonly checkouts.
