It's claimed by some that these changes are visible.  If so, they would 
require a dispensation from the pumpking to get them into 5.22.  But if 
they're not visible, I see the only valid ground to object would be that 
there isn't enough time to soak something that the objector finds too 
complicated, and all the noise about there being better ways to do this 
is completely irrelevant.

If the changes are truly invisible, there is no API to worry about 
committing ourselves to.  (I myself haven't examined the changes to form 
an opinion about their visibility, but the claimed speed-up is very
