I must say that I haven't actually looked at it in detail yet.

I wonder if it could be extended so that processes can attach to
arbitrary shared memory segments (with all the usual UNIX-level
permissions to prevent misuse). The recurring problem would always be
how your different Python processes interpret the memory, although the
details are presumably present in the way POSH in its current state
sets up forked processes.

In any case, I thought that one possibility, given the special nature
of the original Smalltalk system under discussion, would be to employ
POSH in some Web server adapter (such as mod_python) or possibly an
actual Web server itself, if that is where the process forking
actually occurs.
