I'm not sure if it's the best solution not to let (load "filename")
record autoloads.  But letting only (require 'filename) record
autoloads would be a big improvement.  My guess is that the vast
majority of files get loaded by do_autoload and Frequire.
Furthermore, it seems quite easy to implement the recording of
autoloads in Frequire.  I'll give it a try and experiment with it for
a while...

I'm not familiar with this.  Could you elaborate?

When is this used?  Does it load files that define functions that
replace autoloads?
