If the faulty memory is mapped to a user-level process, it can only
crash that process and no other -- certainly not the entire OS.

Incorrect.

Correct.

Virtual memory will be allocated to a process - and this in turn
will be dynamically paged into and out of physical memory (the kind that
has
the actual fault) depending on what else is happening with the system.

And the easter bunny arrives in a few days, the Sun sets in the west,
and, by god, George Dumbya Bush is a total idiot. What other non
sequiturs do you plan on sharing with us?

No. What you wrote is INCORRECT. Windows DOES NOT allocate PHYSICAL memory
to a program - it allocates VIRTUAL memory (allowing the programs to 'enjoy'
more memory than is physically present on the system). The memory management
unit swaps pages of VIRTUAL memory between the swap file and PHYSICAL ram
(The stuff with our theoretical fault).

If a faulty segment of RAM exists it will corrupt the data within that
segment - but it won't normally be a static process that's allocated to that
segment. One moment it might be a chunk of "program A" 5 seconds later it
might be a chunk of "program B" - 5 seconds later it might be a non-resident
portion of kernel code. It will change frequently with system activity; the
less RAM a system has, the more often it will change. And it VERY MUCH has
the ability to crash multiple processes and the OS itself. Been there - done
that - MANY times. Faulty ram on ANY platform that uses paging can bring the
system down.

Nothing non-sequitur about it.
