4408	Atlas crashes on OS X Sierra (10.12)	wraitii		"We've had several reports that Atlas crashes on OS X Sierra aka 10.12 (but not on earlier versions, as it is working for me).

After some debugging with trompetin, it appears to be caused by polling events in two different threads. Specifically, wxWidgets polls events in the original thread (in wxTheApp->OnRun in DLLInterface.cpp) and SDL polls events in RunEngine().
This apparently is not liked by macOS Sierra.

I literally cannot figure out why we poll SDL events in RunEngine, as far as I can tell removing those 4 lines (220-222 of `GameLoop.cpp`) changes nothing. So that's what I'd suggest as a fix?
Could people on other platform check this? And also if anybody knows what those two lines are doing, I'd be happy to know."	defect	new	Release Blocker	Alpha 22	Core engine		rfc
