finite state machine/automaton framework?

Fri Sep 3 10:32:37 PDT 2004

hey,

considering that operating systems in general (and dfly in special) 
have lots of finite state machines in source - most of them hidden as 
evil if/else constructs of which the authors supposedly never heard 
about FSM before.
Is it a good or bad idea to have a (simple) FSM framework available 
which can be used by different parts of the operating system? If yes, 
do such frameworks already exist?

Just a thought because of the need to implement a i8254 PIT emulation...

cheers
