} It's still doing the same impossible thing.
I never saw the previous trace. Looking at this one, I note that it's
doing this impossible thing a lot, but only on fd 10, and sometimes zsh
just ignores the problem and loops. (That would happen when errno == 0,
or if the impossible occurred somewhere other than in getkey().)
Ignoring the problem would mean that zsh discarded at least one char of
input if there really were any, but there's no evidence of input being
lost. That in turn makes me think that reads from the tty are behaving
as if they're non-blocking, but for some reason are returning 1025 when
they should be returning -1 with EWOULDBLOCK.
