I don't like much the pop/push stuff to simulate the call convention.
I understand the changes to properly support it are more involved, but
that's why it hasn't been done yet. Introducing a new opcode like
OP_ECX_THIS should not be too bad, though.
And this codepath needs to be enabled on linux, too.
