Yup. I see the problem. Bare in mind this can only happen if the send()
throws an exception preventing the call from reaching the notifyAll(). Fix
the bad DC for now (or avoid it using lookupRespLimit or something like
that) and I'll put this fix in the queue for the next minor rev.

Thanks for the feedback,
Mike
