(Pdb)

BTW, after I hit 'c' I got:

bzr: ERROR: [Errno 4] Interrupted system call

and it cleaned up the locks, which didn't happen before.

Steps to reproduce:

server> bzr init repo/sandbox
client> bzr co bzr+ssh://bzr@srv1.btrll.com/home/bzr/repo/sandbox sandbox
client> cd sandbox
client> bzr commit -m 'test'

Both machines are linux, server is fedora, client is gentoo.  I have tried
it with all combos of standalone and repo trees.
