- Er, "memory tracking" is better. Generally, anything that allows
- you to core dump will also have memory protection, but this does
- not mean that memory protection is the reason you can core dump.
- There can also be exceptions - for instance, a memory tracking
- system that did not have memory protections (ie, the original
- CAOS operating system).
-
- Of course, I think the real question being asked is not about
- core dumps (which aren't very useful for most people) but rather
- how to have a faulty program not crash the machine. That is
- a matter of memory *and* resource tracking, so that the process
- can be cleaned up completely when it fails. Memory protection
- isn't required for this either, although without it, a faulty
- process may cause other processes to have errors - but won't
- necessarily crash the machine (unless it bumps into the OS memory).
