There are some slow paths in parsing that could be sped up, for sure, but
most attempts to make it faster have thrown out the baby with the
bathwater: they're really fast but don't handle any of the error
conditions, some not even doing multi-server support.
Artur started writing the parsing in XS recently, but got sidetracked.
