Why would that matter?  The user will have to fetch and install a new
package, maybe tweak her .emacs, ... most likely she'll have plenty of time
and reasons to restart her Emacs process at some point in-between anyway.

That sounds like a lot of work for very little benefit: currently files are
loaded by doing an `fopen' and then reading and parsing directly from there,
so it's never put into a buffer where a search could take place.
