"live" streaming (Rails 4.x) likely broken

due magic-threading in ActionController::Live "middleware" ...

This issue seems to be lacking activity, you can change that by posting a bounty.

I can confirm that this causes my application (using trinidad) to deadlock.

Would it be possible to use java threads as a drop in replacement for "magic-threading" (what does that mean?) to get this to work?

Ruby threads use Java threads the problem is the way they're used in Rails - simply not "thread-safe" code. For Trinidad/JRuby-Rack there would be a better solution to this leveraging servlet async support - ideally Rails core would hide the threaded impl under some class that could than be replaced at runtime - so it's some work to be done, go for it!

Is the nature of the problem documented with greater detail anywhere? I'm trying to understand what part of the Live middleware is thread-unsafe.

it dead locks - that's all there is (for now) ... I have not looked deeper and I have not tracked if anyone else did ... sorry

Has anyone tried this against the rails 5 betas? http://weblog.rubyonrails.org/2016/2/27/Rails-5-0-beta3/
