vfork() is a 'light' fork() which you can use if you only fork() to exec()
immediatly afterwards. Since linux has copy-on-write pages for the
child process in a fork() the overhead involved in forking is very low;
on systems which copy the entire address space the overhead is much
higher, which is why vfork() was invented. vfork() doesnt copy
the address space, since its going to be release anyway when you
exec().
