FWIW, I consider automatic shutdown in this case a misfeature, because
this is likely to shut down a session due to some memory-related bugs
more than anything else.  But if others would like that, I won't block
adding it as an opt-in option.

I do agree with Andreas that normally a system will start paging long
before the virtual memory threshold for that warning is exceeded.
