it comes when a file is NOT found, which can happen.

you can't count on that .Suppose somebody builds a bios with fallback
files, and then removes them later. And then adds them back. that's
the beauty of lar -- we can change things.

NOT finding a file should be efficient.

Also, the code looks for payload/segment0, 1, 2, and stops when no
more are found. That 'not found' really takes time. And, we can't
compile this in -- payloads can change too, and the # segments can
change.

So we need an efficient way to terminate the search. Carl-Daniel's
idea is not too bad.
