No speed boost with opcode caches, which will be bundled in PHP 6 :)

Hello Sara,
but if we were moving from flex to re2c for that tokenizing scripts we'd
get a nice speed boost, too. Typically re2c based scanners are 2 to 3 times
faster than lex based ones. And oh-re2c allows unicode scanning (2 byte
input) and you can use the same .re to generate two .c files if necessary.
