For the LPeg test file, v0.11 and v0.12rc2 are about 5 times slower than v0.10.
I know that the new test files are longer, but, when I compare the
runtime with PureLPeg (minus a few tests that it doesn't support yet),
I get a 30x penalty against 0.10, and only 6x when compared to 0.11+
(respectively 25x and 3.7x with LuaJIT)...
I was pretty happy with the 6x difference... 30x is huge :-/
