Tearing down the old classes would be really difficult, since they  
might be referenced by objects that have been passed to the Obj-C  
side. I suppose if you used unique Objective-C class names and just  
cleared the Ruby->ObjC map, it wouldn’t be as bad, but then you need  
extra shenanigans to use Ruby classes from Objective-C.
