Hi,

Compiling the Linux kernel 3.2.12, I've seen this new feature:
KCOPY: "High-performance inter-process memory copies.  Can often save
a memory copy to shared memory in the application. Useful at least for
MPI applications where the point-to-point nature of vmsplice and pipes
can be a limiting factor in performance."

Could Gambit easily exploit this feature to optimize message passing
in multicore machines with several Gambit instances, at least under
linux?
