I believe it is. At this point it's the first optimization I would
consider. There are a lot of attribute lookups that we could get
rid off. Also, slice assignment is often used and probably slow.
But this is just based on gut feeling - I have no quantitative data
to back it up.

Ideas on how to proceed:
* design some profiling test to check whether it's worth the trouble
and what to expect
* intbv is really like a long, so best to start from Python's long module
* perhaps best to use a Python in which int and long have completely
converged?
* on this occasion, review the intbv interface itself thoroughly,
some changes may be worthwhile
