Hi hongzhidao,

The patch wasn't merged as we didn't see much interest and real
technical feedback from potential testers.

The code adds additional complexity to the nginx core with all
associated costs of maintaining the code virtually forever. In the
same time at this point it brings no measurable value to the
community. At least, we haven't seen any proofs that it does.

The patch wasn't updated since that but I suspect it could be still
applied to nginx, maybe with some minor tweaks.
