IME, it is unwise to assign priority to a problem one doesn't have a
sufficient understanding of.  With just a few more details, as would
be revealed by the backtrace from the hang, we could have a much
better idea.  That is why I asked for that.  I myself have no access
to such a system, nor sufficient time to install it and try that.

(A good example of inadvertently ignoring huge problems until they
are pretty much upon us is the ralloc.c incident: I'm sure we had
quite a few bug reports related to that from users who switched to
"bleeding-edge" GNU/Linux systems, but we effectively ignored them as
not reproducible because the crucial evidence that ralloc.c is being
compiled in was never presented.  If we had known this soon enough, we
could have prevented the problems people had with Emacs 25.1.)

Please always report such problems as bugs, using report-emacs-bug.

Thanks.
