Yes, this would at least explain why I couldn't find any OpenMP stuff
in the source code.

OpenMP parallellization is pretty simple to implement if you're
satisfied with a moderate speedup, but getting it to scale more than
90% is pretty hard even in simple cases.

Of course, parallellization only makes sense in those functions that
are actually CPU bound.
