Interesting idea. There is no support for shared memory in Squeak right
now, but in principle it's no different from other OS and C runtime calls
in the OSProcessPlugin. I think that the shared memory interface for Unix
platforms is fairly well standardized, and there are Win32 analogues,
so that it could be provided across most platforms.
