Any, provided they all modularized and support the common communication
protocol.

Does it matter?

"TheThread" abstraction. If it doesn't exist for a selected combination
of language/platform, too bad - probably you made a wrong selection.

"Storage system" abstraction.

Yes.

Doesn't matter

Why not?

At least some kind of smart pointer with a mark-n-sweep or reference
counter, the latter is better in the languages like C++ where it's
possible to have static/automatic objects behave as their dynamic
counterparts (explanation will follow if there's enough demand; I had a
very stable implementation working exactly the same for MS-DOS, Windows
and OS/2, only Java prevented it from existing in UNIX incarnation)
