I already asked that:

  http://lists.gnu.org/archive/html/emacs-devel/2016-10/msg00678.html

The only answer was disappointing:

  I don't know, and would rather not spend time investigating.

It looks like either people don't realize what a land mine we just
stepped on, or they simply don't care enough.

Does it make sense to anyone to release Emacs 25.2 that doesn't work
reliably on recent GNU/Linux systems?  Because that's what is going to
happen if we don't invest all the resources we have into solving this.
