I totally agree with this, I recently got a crash that was due to some ObjC code that was callback'ing a Ruby object in a different thread, and this resulted in a Ruby assertion (IIRC inside rb_gc()). We should definitely print a message to alert the user. Also, if you find any Apple-provided frameworks that are messaging delegate/datasource methods from different threads, do not hesitate to file an Apple bug (https://bugreport.apple.com) and tell me the bug number.
