Eliminating the blockstack would be nice (esp. if it's enough to get frames small enough that they get allocated by PyMalloc)

Someone might like to take a look at the way Pyrex generates C code for try-except and try-finally blocks. It manages to get (what I hope is) the same effect using local variables and gotos.

It doesn't have to deal with a stack pointer, but I think that should just be a compiler-determinable adjustment to be done when jumping to an outer block.
