So it is plausible that Emacs crashed, but didn't leave a core dump
file behind.  Too bad.

I recommend `unlimited'.  I'm serious: there's no way to know in
advance how large will be the memory footprint of your Emacs (or any
other program, for that matter) when it crashes.  The core file that
describes a crash is worth its every byte in gold.

No, I don't think so: if it exited, it would have saved the files, not
leave auto-save files.  I think it crashed.

What was the name of the file?
