Right, and the WorkingTree is locked for the lifetime of the Transform.

It affects the bzrtools import plugin, and anything that calls
TreeTransform.trans_id_tree_path or TreeTransform.trans_id_file_id a
lot. So it also should affect revert and merge, but not build_tree.

The time to execute "bzr import linux-2.6.16.tar.bz2 linux"
