Thanks for the info John. Since the branch merged I've not had an
issue, so didn't get as far as bisecting the history to work out what
changed.

I have downloaded the partial repo from the bug, and noticed that
branching into it takes an inordinate amount of cpu time, which is
probably the cause of the initial hang.

Confusingly though, I can get a similar result branching out of the
shared repo to a fresh tree locally, so maybe whatever the issue was
it was cache related or something. It's possible repacking my local
repo might help, but I won't do it yet in case there's interest in
isolating a specific problem from all this.

That's using the current all-in-one installer, for reproducibility.
For some reason I couldn't get bzr to give me an unmarshalable pickle,
so had to use text profile format.
