Thanks for doing this, it's something I've been hoping someone would do
for a long time.

While I kinda wish we had performance data for each individual patch (at
least the behavior-changing ones), this does look like a good
improvement.  That might, for instance, tell is a bit about how the
separating out "is_lazy" compares to the "check before setting"
optimization.  But, they're both sane enough on their own that I'm not
too worried.

I had some nits that I hope get covered in later revisions, if sent.
But, overall looks fine.  For the series:
