All of this sounds good. The only thing I'd like to do a bit
differently is to pass the reachable commits in prune_shallow() as a
commit-slab instead of taking a callback function. I'll refactor this
code, move prune_shallow() to a separate command prune-shallow and do
the locking thing.
Johannes I could take over this bug too (since I introduced the
shallow pruning and missed this part) if you are busy, but if you want
it to be done fast, I can't help. I still have a list of things to go
through.
