Does it really, under X11?
I'm not sure I understand really how immediate_quit is set up, but at least
I see the following problem under GNU/Linux:

        % .../src/emacs -Q
        
slkfhslafkhslfkgjhsdlkghsdlghsdlfkghlsdfkghlsdfkghlsdfkghlsdfkghlsdfkghskldfjghskldfjghlsdfkghlsdfkghlsdfkghlsdfkghklsdfghskldfjghskldfjghskldfjghskldfjghlskdfjghdkghskldfjg
        M-: (re-search-forward ".*.*.*.*.*hhh") RET

then try to interrupt the search with C-g.  In my case at least it
doesn't work.  Maybe it's because immediate_quit doesn't work, or maybe it's
because immediate_quit is not used in this case, but in any case I find this
behavior to be a problem.
