What kind of effect does this have on optimization efforts, for
example all the stuff done by Antoine Pitrou over the last few months,
and the first few results from unladen? Will it mean we won't get to
the good optimizations until 4.0? Or does it just mean unladen swallow
takes longer to come back to trunk (until 4.0) and every extension
author who wants to be compatible with it will basically have the same
burden as now?
