Is this the first time we've had to add routed objects on this channel? Wow.

[jonathan.backer, 2011/07/22 13:12:40]

AFAIK. I'm pretty disappointed that ChildThread doesn't vend route_ids (same
with MessageRouter for that matter). It seems pretty fundamental functionality.
And if they did vend, I wouldn't have to worry about it.
