A little help with child processes.

[Larry Bates]

Unless you are going to start more than one child
process in parallel and there is enough I/O to
 make it worthwhile, there's no reason for using
child processes at all.  Just program the application
as a single loop.  You can't speed up CPU bound
applications with child processes.
