I'm not sure whether I have understood your point correctly, but
I guess 'bindkey -a "^R" redo' itself isn't causing a trouble.
The problem is the '^R' sent by zletest $'123\C-_\e\C-r'.
The slave-side zsh should set its tty input into non-canonical mode
when Zle is active, but I suspect that it fails (or delays) to do so
and the ^R does has a effect of reprint.

Yes, both on Mac and FreeBSD.
Without the zpty_flush patch, all the tests which use comptesteval
fail (unless the test is the 1st test in X02zlevi.ztst).
With the zpty_flush patch, only the test with 'bindkey -a "^R" redo'
fails. This test succeeds if ^R is replaced by ^K.

Works on FreeBSD but not on Mac (about 50% failure). I don't know why.
But adding 'sleep 1' at the beginning of zletest() seems to work on
both Mac and FreeBSD (adding it after the 'zpty_flush Before zletest'
is also OK).
# Adding 'sleep 1' is to make the last failing test (^R-redo test) to
# succeed (with zpty_flush patch applied but redo is bound to ^R).

Maybe the only call of zpty_flush necessary is
'zpty_flush After comptesteval'
in comptesteval(); all the other zpty_flush call can be removed.
With this single call of zpty_flush and ^R --> ^K, all the test pass
on Mac and FreeBSD (without adding sleep anywhere).
