No, I decided to stick with NAPI for the immediate future.  I'll
look up his work if/when I get time to do some more testing.

Probably not.  Much of it was obtained from Robert Olsson's
patch, and then I added some more tweaking.  It sounds like there
is little or no interest to support tulip NAPI in 2.4.X, so my
goal was to play with things, rather than try to feed a patch
to an official maintainer.

However, I would love to hear suggestions as to how to make this
better.
