I take that back. The intertwinement of C functions and Python calls on
the stack makes this nearly impossible -- there's no easy way to pop both
the C and Python stacks before calling the next function (it could be
partially done popping only the Python stack, though). Methinks tail calls 
will have to wait for Stackless.
