One thing that jumped out at me is that you call FreeSpaceMapExtendRel
every time a rel is extended by even one block. I admit I've not
studied the data structure in any detail yet, but surely most such calls
end up being a no-op? Seems like some attention to making a fast path
for that case would be helpful.
