Well, it does look like we need to enhance the verifier (both
in the compiler and the interpreter) to handle interfaces as discussed
earlier.  While this is only needed to catch bogus bytecode, and isn't
top-critical, it does need to be done.

Kresten, can you summarize how you did this in your verifier?
Perhaps your slides from jaoo'99 may be enough.
