I like this, esp. if for old releases the collision counting is on by
default and the hash seeding is off by default, while in 3.3 both should be
on by default. Different env vars or flags should be used to enable/disable
them.

Really? I'd expect the difference to be more than 2 nines. The randomized
hashing has two problems: (a) change in dict order; (b) hash varies between

The text speaks about the regular case of a second character that
