That's true, but the extent to which it's true varies considerably
from one OS to another. Starting processes is typically very cheap on
Unix systems. On Linux a thread and a process are actually both
started by the same system call, and the only significant difference
is how some of the new page descriptors are set up (they're
copy-on-write instead of shared).
On other OSes, starting a process is _way_ more expensive/slow than
starting a thread. That was very true for VMS, so one suspects it
might also be true for its stepchild MS-Window.
