  Looking just at the Linux man page, EAGAIN is not in the list
of potential error returns for poll(2), but when looking at one of
the OpenGroup pages on the function
  http://www.opengroup.org/onlinepubs/009695399/functions/poll.html
it allows EAGAIN, so I just changed EINTR to EAGAIN, in this function
and pushed the change,

  thanks !
