[$] Moving beyond fork() + exec()

Description:
Since the earliest days of Unix, two of the core process-oriented system
calls have been fork() , which creates a child process as a copy of
the parent, and exec() , which runs a new program in the place of
the current one.  In Linux kernels, those system calls are better known as 
clone() and execve() ,
but the core functionality remains the same.  While there is elegance to
this process-creation model, there are shortcomings as well.  A recent 
proposal from
Li Chen to add "spawn templates" to the kernel will not be accepted in its
current form, but it may point the way toward a new process-creation
primitive in the future.
