Is it an EMULATION of OS9? Could that be why OS9 applications seem

Here's what it "virtually" looks like:
Mac OS X

Classic Environment <-- an OS X application that
creates the "virtual environment" that makes
OS 9 "think" it controls the Mac's hardware.
\
Mac OS 9 <-- the real thing (+/- a few drivers)
\
Your classic application
IOW, it's real OS 9. BUT when OS 9 tries to do something that
involves a peripheral (screen, mouse, keyboard, hard drive, etc),
it's actually talking to Classic which in turn talks to OS X. This
level of "abstraction" is not perfect, nor is it very fast...
