Let me know, at any point, if you need otherwise.

Oops... sorry, Eli, first thing I did.  I did not even consider not 
doing it.

What follows is from a different session/crash, but I included the first 
info anew. I'll try to keep this session alive this time (I've used a 
named server for this, since it's my main computer and I'd like to keep 
using Emacs regularly in it in the meantime).

The output from all commands you've asked so far for this session is:
