   No, vfork() is very different.  vfork() suspends the parent process
   until the child process calls exec(), in order to avoid the potentially
   immense overhead of copying the whole memory space.  Linux doesen't
   need a separate vfork() because its fork() just marks things as
   copy-on-write.

Good grief, you're right.  I've had this misconception for some 15 years.
Somebody told me long ago that `vfork' did copy-on-write, and I never checked
the `man' page.

What a disillusionment!  Next you'll tell me there's no Santa Claus :-)
