[clean-list] calling heaven from hell

If you are going to do that kind of upside-down inside-out programming,
you should find the book by Michael Jackson on Jackson Structured
Programming, which dates from around 1980.  He developed a style of
program design that was based on coroutines.  Unfortunately, the 
programming languages commonly used then had no support for coroutines.
Jackson solved that problem with some programming idioms applicable in  
Cobol, etc, that would let one return from the middle of a loop and
go back to finish the loop when the next call came in.  Fortunately, 
I suppose, Jackson moved on to bigger and better things, and you don't
see much of this JSP code around.  But his old book gave lots of gory
details.
