I realize what it's for, and I don't agree that it belongs in the
tree. There are other forms of interprocess communication, pipes,
sockets, even msg queues. I'm sure you can find a few ways to send
a message to a process to say "send signal X to thread Y" if you
really wanted to. It looks like even Linux makes you use a thread
group, not a thread.
I don't see where this was discussed on -arch or -current, but
maybe I missed that thread.
