   For operating systems like VMS and WNT that cannot fork (duplicate a   
   parent virtual space into a child) Posix allows spawn() instead.   
      
   Spawn is equivalent to fork()/exec() and CreateProcess() in that   
   it creates a new address space, loads an exe, and starts a thread.   
   Like fork() and WNT CreateProcess(), spawn() allows open file descriptor   
   handles to be passed to the child.
