Now for the testcases... ;) Seriously, I have no idea what's the "policy" about
this kind of optimization, how many testcases are normally added, in principle
if one wanted to minimally exercise every code path would be dozens, I guess.
Personally I would be more interested in knowing how many times the new code
triggers in eg, a bootstrap.
