There's a reason MvL is doing this on a branch - the idea is to benchmark the 
status quo (which he's done), merge int & long into a single type (which is 
naturally the current PyLong, as it is a complete functional replacement for 
int, albeit slower), and then optimise the C level integers *inside the long 
type*.

If the merged type can provide comparable performance to the two separate 
types, then it can become the 'int' type in Py3k, with 'long' being a 
historical relic existing only in the 2.x series.

Cheers,
Nick.
