I've been playing around with the newest commits to 7.9, in particular a change made that should allow PollDeviceBackend and PollBackend to co-exist. Specifically, I'm trying to get things to compile on OSX, and while I think I've accomplished that goal, it doesn't appear that the resulting PollBackend works (at least all of the tests fail).
I seem to remember that being true on OSX, as poll isn't really fully functional. Can anyone confirm that? I don't see any point in committing my my fixes to get both working if the result is non-functional (in which case I'll commit a fix that disables poll on OSX).
