Autload thread safety in Ruby 2.0?

Rails
1

Jose Valim implies that autoloading is threadsafe in Ruby 2.0:

The issue with this approach is that it is not thread-safe, except for

latest JRuby versions (since 1.7) and Ruby master (2.0)

However, the autoload bug ticket filed against Ruby
(Bug #921: autoload is not thread-safe - Ruby master - Ruby Issue Tracking System) was closed and refers to a forum
post wherein Matz recommends not to use autload
(http://www.ruby-forum.com/topic/3036681).

Does anyone have any light to shed on this discrepancy?

Here’s a link that’s a little more current that sheds some light on the
issue: Don't autoload? · Issue #45 · sinatra/rack-protection · GitHub

Thanks, Rick. I’ve asked the question on that thread as well. It seems
to
suffer from the same issue: its just a claim that appears to conflict
with
Matz’s implication from the same post I included in my original
question.
