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.
