I wasn't seeing the problems reported, but the patch works in the
following sense:  I have a test script

foo=$(sleep 10; id -u)
print "foo=$foo"

which I ran with a background zsh.  I sent that a SIGWINCH while the
$(...) was sleeping, and without the patch the final message was

foo=

while with it I got

foo=295

which is correct.  This appears to be repeatable.
