This sentence was not accurate.
Correct expression is:
even if the processes don't use same virtual memory space.
Acutally, the POSIX specification implicitly assumes that the
processes share same memory (via mmap or something).
Although it doesn't assumes that the processes don't use same
memory space (like parent and fork()ed children).
