Find any idea you want, it just won't work. There are remains of tries
to
add memory protection in the Amiga Kernel. But since it hasn't been
since
the beginning, we can't go back now.
Of course memory protection should use the MMU, there's nothing other.
The
only type of protection existing now is based on semaphores, but still
few people use it. WarpOS and Enforcer do some memory protection, but
they
protect areas of memory where noone should write or read. They both
can't
prevent some task from trashing other's memory.
There are a huge load of programming tools designed for testing
programs in any conditions. Most of them are available for free on
Aminet
or in the developper CDs but still noone use them.
So There's no doubt if people use these tool, the softs will be really
more stable, and the whole system with them, it's just a human problem.
