Ksm is code that allows merging of identical pages between one or
more applications, in a way invisible to the applications that use it.
Pages that are merged are marked as read-only, then COWed when any
application tries to change them.

Whereas fork() allows sharing anonymous pages between parent and child,
ksm can share anonymous pages between unrelated processes.
