Ahh.

This is much nicer than what I was playing with yesterday, trying to 
separate out the "bool group" logic in the signal sending code.

I didn't even think to use the pidtype. 

In my defense, I would never have done this whole pidtype cleanup that 
preceded this patch just to fix that odd fork() thing.

As I started reading this patch series, I went from "this seems a bit 
pointless" to "Ahhh...." and as I did that I started liking the series a 
lot more.

My initial reaction was "this seems over-engineered" when I just looked at 
the subject lines in my mailbox.

But as I progressed through the series, I really appreciated it. And this 
"10/11" was when I went "ok, I don't even need to see patch 11, I know 
what he's doing.

Anyway, take that as a long-winded ack for the approach and the 
appreciation of the series.

Of course, that's just reading through the patches, no actual _testing_ of 
them. But it looks good to me.

Thanks,
