- update to 1.7.1:
* :bug:`659` Improve behavior under ``nohup``, which causes stdin to become an
undetectably-unreadable (but otherwise legit) file descriptor. Previously
this led to `OSError` even if you weren't expecting anything on stdin; we now
trap this specific case and silently ignore it, allowing execution to
continue. Thanks to ``@kingkisskill`` for initial report and to Ryan Stoner
for followup and workshopping.
