You have. Due to the lack of a concurrent GC, OCaml doesn't allow multiple
threads to be executing caml code at once. This means that OCaml (unlike,
say, C) doesn't allow you to take performance advantage of a multi-CPU (or
multi-core) machine by running multiple threads in the same executable. With
the predicted rush of multi-core CPUs, the argument can be made that being
able to take advantage of this kind of paralellism is increasingly
important, and a feature that should be on OCaml's roadmap, which it
currently is not.
