Something inside me rebels at using side-effects from a declaration
like that. I can't really talk; my database library unlocks objects
as they go out of scope, but ... well, I know that code gets executed
in declarations, but I don't necessarily want to be this aware of it.
On the other hand, it's just a monitor, I shouldn't be so scared :)
cheers,
Fraser.
