Research direction
Start by reproducing the example on mruby 3.0 with the mruby-thread extension, defining AAA in the main thread and instantiating it inside Thread.new. Trace the thread handling and class/module lookup involved in that failure; done means the child thread can instantiate AAA and access main-thread classes and modules without the undefined class/module error.
