My suggestion is primarily about using multiple threads and sharing

mentioned.

Good luck with that. The GIL is not going away any time soon (or
probably ever) and as long as CPython is the "official"
implementation, there are almost zero chances of adding syntax support
for this. Besides, Guido and other py-devs are not particularly keen
on threads as a parallelization mechanism.
Parallel processes can run on multiple processors as well as multiple
cores within a processor. Some problems, like massive search, require
multiple disks (or memories, or IO ports) as well as multiple processing
units. There is debate over how useful massively multicore processors
will actually be and for which types of problems.
