Title:
  epoll_wait man page error

Status in The Linux Kernel:
  Unknown
Status in manpages package in Ubuntu:
  Fix Released

Bug description:
  man epoll_wait states:

  EINTR  The  call  was interrupted by a signal handler before any of the
                requested events occurred or the timeout expired; see signal(7).

  However, epoll_wait does not return EINTR when the timeout expires, it
  simply returns 0 as number of file descriptors, and errno = 0.
  This is the correct behaviour (otherwise there would be no way to tell
  a signal interruption from a timeout one).
