Yes, that's what I'd like to do in the long run. Emacs shouldn't be in the
malloc business.
If the hybrid malloc approach suffices to get Emacs to work with the new glibc
API (and assuming Emacs doesn't already work with the new glibc API), then we
could install that patch series into emacs-25 rather than trying to improve it
for after Emacs 25, on the theory that people will want to build Emacs 25 in
GNU/Linux environments with the new glibc and that this boosts the urgency of
the hybrid malloc.
Florian, I understand that the new glibc implementation doesn't exist yet, so we
can't test Emacs on it. However, is the new glibc API documented anywhere?
Perhaps we could try to check via code inspection that Emacs works under
GNU/Linux both with the current and the new glibc API, either now or with the
hybrid malloc patches installed.
