So pretty consistent here, apart from the glitch on the first "after" run, and about an 80% speedup.
Yawn . If someone wants to run with this, be my guest. There may be other holes (c.f. PyListNew above), and it could sure use a comment about why it's correct (if it in fact is <0.9 wink>).
I'll look at the this this weekend.
The improvement is awesome. Hope it has doesn't muck-up anything else.
