The answer is `yes, you have to, but it doesn't cost nearly as much as
you think it does'

It wouldn't be too hard to set a little hack where each class has two
extra fields:

MonoClass* first_child
MonoClass* next_sibling

This would allow us to easily just look at the people who derived.

Also, why do you need to patch the actual vtable? Isn't the address to
the method going to be embeded in quite a few places anyways?
