locking during relink

[Koen Van Hoof]

Hi,
In relink.py I see
 Â Â Â  with repo.lock(), src.lock():
 Â Â Â Â Â Â Â  candidates = sorted(collect(src, ui))
 Â Â Â Â Â Â Â  targets = prune(candidates, src.store.path, repo.store.path, ui)
 Â Â Â Â Â Â Â  do_relink(src.store.path, repo.store.path, targets, ui)

Is there any reason why the the collect and the prune have to be inside 
the lock ?
