I don't. I mean, not conceptually. I want to call all signal handlers 
that happen to be connected at a given time.

Maybe I'm thinking about this the wrong way, but to me, "just calling 
the signal handler", doesn't really seem like a great idea anyhow, at 
least in anything but a very simple setup - as in my experience, if you 
have two completely separate pieces of code that are supposed to do the 
same thing, in real life they very often don't - if you know what I'm 
saying...
