I had one of my own.
Does this fix it?
It uses the "raw" version of 'for_each_ref()' (which doesn't verify that
the ref is valid), and then does the "type verification" before it starts
doing any gentle commit lookup.
That should hopefully mean that it no longer does tons of object lookups
on refs that it's not actually interested in.
