I'm not sure what could be done about this from the zsh code.  The
only reasonable assumption for the pty master-side reader is that the
slave-slide will become closed upon an error and the read will fail.
Using a non-blocking read would defeat the purpose.

I suppose we could skip the test on OpenBSD, but there are a bunch of
later tests that rely on zpty functioning.
