Re: zsh 5.6 regression: a pipe sometimes yields a TTOU signal

[Vincent Lefevre <vincent@xxxxxxxxxx>]

As a workaround, putting the middle command in { } can help a bit.
For instance, instead of

  echo foo | { cat | less -+c -FX }

writing

  echo foo | { { cat } | less -+c -FX }

seems to avoid the issue most of the time, and

  echo foo | { { sleep 0.001; cat } | less -+c -FX }

is even better.
