RETE patch for faster forward rule execution
I would like to like to submit a patch which speeds up forward rule
execution in the RETE engine.
It uses only slightly more memory, but reduces the time needed for my
dataset of about 100.000 triples from beyond measuring to about 5
minutes.
It passes all tests so far. Am I missing something?

Hi Dave,
Everything seems alright.
Thank you for applying the patch. Now I don't have to patch Jena in my
projects manually.
Bye, Tilo

Hi Tilo,
The patch looks good to me. As you say there is a space cost but the
trade-off seems reasonable.
Andy has created issue JENA-412 to track this request. I've checked and
applied the patch. If you give it 24 hours for the snapshot builds to
propagate then you can check whether 2.10.1-SNAPSHOT correctly includes
your patch. If so let us know so we can close the issue.
Many thanks for your contribution.
Dave
