I was just thinking the other day about the A2500, MMU's and Unix interfacing
to AmigaDOS/Intuition...

I realize that much of the Amiga system passes pointers back and forth
(messages and message ports are used extensively for I/O among other things).
And many (make that many many many) structures include pointers to other
things that they'd use.  I was just curious as to whether there is a movement
afoot for 1.4 (or would it of necessity be 2.0) to provide intermediary
support for proper intertask communications without the MMU "getting in
the way".  In other words, a library that provides, among other things,
registering a new task with a resource manager, full resource tracking
for that new task, creation and management of what we might have normally
considered directly modifiable data structures and functions that would
manipulate those structures for us.  In other words, if there would be
a master task, whose MMU entries managed all of CHIP RAM, such functions
would become a necessity and perhaps a new VIRTUAL version of the sharable
libraries would need to be created.  I do realize that this does add
overhead, such as message copying (unless explicitly using SHARED RAM)
but that may be the price one has to pay for beginning to use an MMU.

Again, just a curiosity on my part -- is this part of the plans for 1.4,
or am I just dreamin'?
