OK, I think you were just unable to take advantage of threading in EM
via app.deferred?

I think you also need to enable threading in Rails, too.

Probably not, this needs to be visible at the Rack layer, not Rails.

See what Mark just said.  Also, t/app_deferred.ru in the rainbows
source[1].  There's also a link to Ezra's old post about it in the
TryDefer documentation.
