For Rich, Mike, and others (I may have mentioned this before, but just
in case...)

I had rebuilt snort 2.8.6 with libpcap 1.1.1 and had some worse
performance than before, but then there was a discussion on one of the
snort lists regarding sids 4676 and 4677 in the oracle-rules being a
pcre "hog".

Disabling those two sids dropped my average CPU over half...
