I think he mean "under" in the sense of "Firefox runs under both windows

I think it had virtual memory but not dynamic paging. (To have dynamic 
paging, you have to be able to restart an instruction that accesses 
invalid memory, so you can restart it after you page the data into RAM 
from disk.)  Some applications used it, tho - photoshop did, I think.

Isn't OSX based on POSIX at least?  The stuff *I* liked about the Amiga 
is all missing from POSIX, as far as I can see. :-)
