If that's the case, shouldn't we switch such glibc systems to use mmap
instead?  It should be free of at least some of the problems in
ralloc.c, I think.

Alternatively, how about supporting an external Doug Lea malloc
library (assuming such a library exists and Emacs can be linked
against it)?

ralloc.c is generally "bad news", we've gone to non-trivial efforts
during the last years to reduce its usage to the minimum.  I always
thought that only MSDOS and perhaps a few *BSD systems still use it.
Having it creep back into GNU/Linux is really a bad regression, IMO.
