Classic environment query

[beachycove]

Does Classic under OSX benefit (indirectly) from the Unix foundation it runs on: Is it, in other words, in any sense multithreaded, or does it run in a single unix "thread," is there protected memory, and does it have any advantge viz. preemptive multi-tasking etc.? Or is Classic simply what MacOS always was, effectively self-contained within some wider unix process?

System 7 under A/UX was single-threaded, did not offer protected memory, and offered only the standard, limited MacOS multitasking capability of plain-Jane System 7, so is MacOS9 running under OSX effectively the same?

It just virtualized like an OS in Parallels or VMWare. So... the whole Mac OS Classic incl. it's applications run as one UNIX process if I am right. :-x

I wish they had Classic Support for Leopard PPC users and BootCamp for the Intel beasts.

Does Classic under OSX benefit (indirectly) from the Unix / System 7 under A/UX / is MacOS9 running under OSX effectively the same?

No, and yes.

It is a pity but modern Apple wouldn't entertain that. They have already
