Yes, it's feasible. It is on my list of things of do. Admittedly I'm stretched 
thin, and the approach I prefer (generating and then compiling C code) is not 
everybody's favorite.

That would be more work than fixing Emacs, I expect. Plus, malloc hooks are not 
the only reason  unexec is dicey.

I don't think that will help. Similar problems likely affect 24.5 and earlier 
versions, if they are built against bleeding-edge glibc and are configured in 
the default way.
