Yeah, bitstring suffers from this a little bit too. Not to this
extent, but certainly processing our generated file of kernel parsers
(two levels of generated code) can take 45 seconds whereas a normal
invocation of ocamlopt is sub-second.
Perhaps it's worth just checking that your machine isn't running out
of physical RAM and thrashing. The OCaml garbage collector performs
very badly when this happens.
