Julia not recognizing/handling end of input stream

[kmsquire]

At a bash prompt, the following hangs:

$ for ((i=1; i <=10; i++)); do echo $i; done | julia -e 's = 0; for _ in each_line(STDIN) println(s); s += int(_) end; println(s)'
0

During the looping, uv__epoll_wait is returning events==UV__POLLHUP, which isn't handled in uv__stream_io so no callbacks are triggered and we just keep going around the event loop.
