   Yes - if we _force_ resource protection/tracking upon them.

[ Well known and correct example of problems herein deleted. ]

   Now, if a few hooks where in there to allow applications to explicitly ask
for protected,virtual and non-shareable memory, (AllocVMem() ?) they could
benefit on the larger machines, while still running on non-MMU machines. The
programmers of large, ram-intensive applications would embrace this.
   They would still use AllocMem() for message ports and whatever else is
going to be shared with other tasks.

   For non-MMU machines, these calls would behave just like AllocMem(),
apart from the resource tracking.

   Would this break anyone? Valentin?

   That's real nice. The OS doing so, or some devilish debugging tool?
