Everyone: this program seems to be a direct and misguided 
transliteration from a bash script.  There are dozens of mis-uses like 
this of multiprocessing.Process(), due to a severe misunderstanding of 
what it does and how it works.

We've tried offering help, and all that's happened is we've been told 
that this strange coding style is easier to read.
