I think I was confused...

The main patch that I am concerned with was merged quite some time ago
in commit 31efee60f489c759c341. The other one needs more work before we
can merge it, I think.

That problem ought to be more rare though. Basically, you'd need to
have the task catch a signal before sending anything on the wire. I'll
see if I can clean that patch up later today and will send a draft of
it.
