I did try out sending various signals to the bash process.
Some, like HUP, close the xterm and its emacs child, but
there are signals, like ABRT, that close the xterm but
leave the child in the care of /sbin/init.
So, for example, you can still paste your large copy into
the (emacs) child and at least get that safely stored.
But I didn't find any signal that could regain control of
bash once you've given it indigestion, so the & idea is
still my only suggestion.
Cheers,
David.
