Re: binary switching, no killing

[David Ford <dford () erisksecurity com>]

Modularize your functions and use a process unique (a|b) id; 
function_123 loaded at startup, function_124 loaded later, load the new 
module function_124, migrate data sets as needed, lock data sets, 
deregister function_X -> function_123, register function_X -> 
function_124, unlock data sets.  If your code works properly, all you 
need is a function shell structure and you can continue this for a long 
time.
