Cute.
You could also just have a pointer to this function in the Class
object. That way, for a reflection-less install, you could even
remove the reflection-related fields from Class. This would require
hacks to natClass.cc and probably other places, though.

Sounds reasonable to me. I don't think you even need to change the
runtime very much... it looks to me like the runtime linker already
skips this step if the 'idt' field is set.
Building the idt table at compile time, for the C++ ABI, seems like a
general improvement. I don't think we need this to be conditional on
-fno-reflection.
