Milestone:  To Be Determined                |   Component:  asio          
  Version:  Boost 1.49.0                    |    Severity:  Problem       
 Keywords:                                  |

 The relevant code:
 #if defined(EPOLL_CLOEXEC)
   int fd = epoll_create1(EPOLL_CLOEXEC);
 #else // defined(EPOLL_CLOEXEC)
   int fd = -1;
   errno = EINVAL;
 #endif // defined(EPOLL_CLOEXEC)

   if (fd == -1 && errno == EINVAL)
   {
     fd = epoll_create(epoll_size);
 ....

 with glibc 2.13 EPOLL_CLOEXEC is always defined but epoll_create1 may
 return ENOSYS which causes the code below to fall though. The proposed
 patch is attached
