No, that's not to imply that 1.4 will have built-in virtual memory, or that
1.4 will be out by the end of the year.  I'm just predicting, based on what I
know about MMU's, the Amiga OS, and all, that a virtual memory manager will
be available in some form by year's end.  Someone's already done one for the
Mac, and it didn't require an OS revision.  Similarly, I believe such a memory
manager would work under the current Amiga OS.  Virtual memory doesn't imply
protected memory, however, and in fact, while I think I know how a virtual
memory manager would work, I'm not sure it would be feasible to add-on memory
protection -- that may have to be part of a new OS release to work correctly.
Though I do know of people who've played with the idea....
