This has been repeated ad nauseum, but it seems another time is
needed:
Writing SW system-friendly and even OS4-native has no relevance to the
SW being ready for full(real) MP.
The whole Amiga-API with it's open system-structures, pointers to
structures inluding pointers to structures including pointers.... with
message-passing done by poking into the other tasks memory and so on
is fundamently incompatible to MP, and a whole new set of APIs would
be needed to get MP.
One could either do it by boxing in the legacy-API (like done in OSX
and WinNT/XP), or hope that both worlds will work under 1 kernel
(Win95/98/ME).
