 python -m timeit -s 'from bzrlib.repository import Repository'
'r=Repository.open("bzrrepo");r.lock_read();len(r.revisions.get_parent_map(r.revisions.keys()));r.unlock()'

If you could run this against e.g. your emacs repo I'd appreciate that.

This isn't quite the same as walking the dag, because we're just loading
everything in.

Doing a spider operation:
 python -m timeit -s 'from bzrlib.branch import Branch'
'b=Branch.open("bzrrepo");r=b.repository; g=r.get_graph();
r.lock_read();
s=g._make_breadth_first_searcher([b.last_revision()]);list(s);r.unlock()'
10 loops, best of 3: 2.47 sec per loop
