I think the attached patches would work for Emacs 31, but are almost 
certainly too risky for Emacs 30. The first one especially changes some 
very fundamental parts of Eshell, though happily in a way that 
simplifies it a bit overall.

The original patch I posted is probably the safest for Emacs 30, since 
it's only a slight tweak to how we kill processes when their output pipe 
breaks.
