I mean Emacs is no longer frozen.  This is the only practical handling
of this situation that we could provide for such files.

The results of incremental search are shown as long as displaying them
takes a reasonable amount of time.  When Emacs is no longer capable of
displaying the results in reasonable time (a.k.a. "freezes"), the
results are no longer displayed, to give you a responsive Emacs
session.
