} Usually a SIGPIPE is generated by a write on a descriptor whose "other

} but it shouldn't exit at all?

Behavior before patch:

torch% (sleep 5; echo hello; print -u2 continued after PIPE) | (exit)
torch% 

Behavior after patch in 33257:

torch% (sleep 5; echo hello; print -u2 continued after PIPE) | (exit)
echo: write error: broken pipe
zsh: write error: broken pipe
continued after PIPE
torch% 

No history saved in either case, so at least that part is OK, but the
patch obviously breaks something in subshells.
