I have no further technical comments.  As for the politics of dropping
emacs support, you're on your own ;-)

Emacs is still fully supported. With the heap rewriter, existing binaries still work (despite the alignment fix on ppc and other architectures).

Current Emacs sources should compile fine as well:

  http://debbugs.gnu.org/cgi/bugreport.cgi?bug=22086

I'm not sure if these changes are actually needed. After removal of the hook, the existing configure test will fail, and newly compiled Emacs binaries will interpose their own malloc implementation. But removing additional deprecated functionality from <malloc.h> probably does not hurt.

I'll do some compatibility testing once we have the final set of malloc changes for glibc 2.24.
