Hi Tatsuo,

The NFA executor code looks stable to me at this point. I do have some
additional optimization ideas around absorption, but I think it's better
new features should be added more carefully, or deferred until after the
commit.

Please go ahead and release v44. Having a fresh patch set will also
make it easier to proceed with the next round of test modifications
and improvements.

Best regards,
Henson
