I think that's probably just the main thread, again. fd 4 seems likely to be
the listening socket (I'd expect 0, 1, 2 are stdio, and 3 to be the ~/.bzr.log).
So this thread is just polling the listening socket for new incoming
connections, I think, which is normal and correct.

Try looking in /proc/<pid>/task for PIDs of the thread(s), and stracing those.

Thanks for your persistence!
