: Thanks for trying that out, it's good to hear that the problems have gone away. On the tight loop theory then can you check if a small sleep, or may a Thread.yield, causes the dup2 hang to go away too? Sure I can give that a try. I'll try to get the dump you requested earlier if not. That would be good.

:

On the patch, are you submitting it here as a contribution (once you are done with your testing)? I haven't looked at it closely yet but I think it is close to what we have in the epoll Selector. Yes I just reused the same approach that epoll is using with slight alterations, since it seems to work well. The patch if useful is a contribution, although as you noticed its mostly a derivative. It make sense too. I've created a bug to track this:

7191587: (se) SelectionKey.interestOps does not defer changing the interest set to the next select [macosx]

and once you are done with your testing we will look to get this into jdk8. Once we are satisfied they we can seek approval for 7u8.
