Is anyone working on callcc for OCaml?

If the answer is no, and I want to use lightweight
threads, I can program in CPS to make my own
(non-preemptive) thread system.  Would large programs
written in CPS incur any particular extra overhead
from the current OCaml compiler/runtime?

An unrelated question: suppose I have some combinators
or whatnot that I use all the time.  If they are in
their own file, then I assume I pay a
cross-compilation module penalty every time I use
them.  Is there a way to #include them instead?

Thanks!
