Yeah, lazy fetch codepath seems to be, eh, not quite well polished
yet.

I am kind of surprised that there is no trace2() events around
promisor_remote_get_direct() or its callers.  Perhaps it is a good
idea to add one to log how often it is triggered, and how large a
batch the callers of the function is making?

Unlike the diff machinery, blame does not have a prefetch machinery.
I am glad that somebody is looking at it.
