Hi Andrea,

Thanks, I had trouble figuring out what this parameter meant.  Maybe we
could improve its documentation.

BTW, what is the purpose of the LOAD parameter here?  Is it just a
convenience feature to allow a user to load the file after compiling?
I'm asking because that option was recently made obsolete for
`byte-compile-file'.

So when loading a byte-compiled file, Fload should check if there exists
an entry for this file in `comp-files-queue', and if there is one,
change its load property to `lazy'?  Do I understand you correctly?
Sorry if I'm not very clear, I'm still trying to understand all this.

OK, I'll add such an option.
