And it's not always the "best thing" to do: If a process is
killed for whatever reason, a parent process might think it
is a good idea to spawn a new process that then starts to
behave the same way the killed process did.

Because disk space is cheap today, I tend to create swap
partitions everywhere. If they aren't used - fine. But in
a case where swap space is expected, due to "memory is full"
or "I want to write a core file", it doesn't harm, and in
worst case it can be ignored. :-)
