If epoll_wait() reports EPOLLHUP, we must respond immediately and unregister the event or else Dispatch will go into a spinloop. This makes dispatch_io_pipe_close (#476) pass on Linux with identical output to Darwin.

@swift-ci please test |
|
Maybe add the test from Johannes PR to this? Then we have the test and impl together? |
|
@gottesmm - I don't think that matters if we commit them at the same time. They should remain individual commits to retain the authorship information. |
|
@compnerd you can keep the authorship information the same and have a different committer. @adierking Can you just cherry-pick that commit into this PR and do a test and merge. Lets get this in. |
|
I created a combined PR for this to get this going. I am going to close this to eliminate confusion. |
|
Thanks - I've been busy and I haven't been able to update this. |
