The great thing about the hash is that you can alloc just the hash
itself, but not bother duplicating the stuff in the array into the
hash's pool. That is, there should be no lifetime concerns. So I
don't think you'll be, say, doubling the amount of allocation for the
commit items or anything.

Actually, I was a bit confused as to why the deletion step occurred at
all. Can the commit driver not simply skip over those things as it is
looping over the list?
