Arnaldo Carvalho de Melo 6dcf45ef98 perf record: Filter out POLLHUP'ed file descriptors 
So that we don't continue polling on vanished file descriptors, i.e.
file descriptors for events monitoring threads that exited.

I.e. the following 'perf record' command now exits as expected, instead
of staying in an eternal loop:

  $ sleep 5s &
  $ perf record -p `pidof sleep`
