Let's install this this on master, then.  The use cases which trigger
the problem are rare enough to not be too urgent to fix.  Moreover, we
might decide, for different reasons, to bump up the stack size of the
Emacs binary, which will indirectly fix this problem by making it less
probable.

Thanks.
