To make at least some users happy: it is indeed possible to exploit
SMP-machines with native threads in OCaml, but those benefits only occur
when calling external functions that do not interfere with the OCaml
runtime. E.g. LACAML (the LAPACK-interface for OCaml) makes use of this,
which means that you can, say, crunch several matrices in parallel. Due
to the elegant handling of threads in OCaml, this is much nicer to do
than in C.
