Newer versions of PCRE have a JIT: http://en.wikipedia.org/wiki/Perl_Compatible_Regular_Express...

V8, SpiderMonkey, and jsc also all have regular expression JITs.

I believe pypy also has a regex jit.

Yup we do.

SpiderMonkey uses JavaScriptCore's regular expression JIT, YARR (Yet Another RegExp Runtime).
