illumos gate

The following program fails on linux with "epoll_ctl: Operation not permitted", but succeeds on fresh OI (illumos-gate from August 7) when /tmp/1 file exists:

#include <stdio.h>
#include <sys/types.h>
#include <sys/epoll.h>
#include <stdlib.h>
#include <fcntl.h>

int
main (int argc, char *argv[])
{
  int sfd, s;
  int efd;
  struct epoll_event event;
  struct epoll_event *events;

  sfd = open("/tmp/1",O_RDONLY);
  if (sfd == -1) {
      perror ("open");
      abort ();
  }

  efd = epoll_create1 (0);
  if (efd == -1)
    {
      perror ("epoll_create");
      abort ();
    }

  event.data.fd = sfd;
  event.events = EPOLLIN | EPOLLET;
  s = epoll_ctl (efd, EPOLL_CTL_ADD, sfd, &event);
  if (s == -1)
    {
      perror ("epoll_ctl");
      abort ();
    }
  return 0;
}

On Linux it fails with epoll_ctl: Operation not permitted.
This leads to test_selectors.py python 3.4.7 test failure.
