Marcel, this is nice stuff, isn't it? :)
I would suggest that 'poisoning channels' is exception-handling and
'poisoning processes' is termination-handling but not
For example, exception handling could perform graceful termination
(i.e., poisoning a process) or it could perform some sort of recovery
without termination, e.g., retrying communication.
Poisoning processes and poisoning channels are two different concepts.
We need definitions to clarify both concepts.
'Poisoning channels' will be supported by CTJ in the next upcoming
David May once said in a discussion panel something like "It takes no
skills to add more functionality, but it takes skills to leave things
out which are not really necessary". Now that is what I call occam
philosophy :) .... hmmm, this is also Java philosophy, hehe.
