You can try this:

    () {
      zmodload zsh/system
      local REPLY
      while sysread -t 0.1; do done
    }

This reminds me of a student in a C programming class who was
frustrated by the pesky "core dumped" message printed after his
program succeeded. He redirected stderr to /dev/null
and--Voilà--problem solved!

The teacher wasn't convinced by this "solution" and neither should you.
