It is user-visible. If you visit a file asynchronously, Emacs is still
responsive, and you can run other commands. For example, during
asynchronous loading of /ssh::~/src/emacs/admin/* I was still able to
call gnus and read my emails.

I was thinking already about. find-file-asynchronously could be a regexp
or a function, determining whether a file should be visited
asynchronously, or not.

I will play with these proposals.
