I'm running the testcase (without the fix) and I'm getting a number of different errors. What error do you get which shows this problem?

Also, I'm not sure the fix is correct. I don't think it's possible for receiving to be false, while stopReceivingBefore is false, because there's a lock,   
{code}
boost::lock_guard<boost::mutex> lock(receiving_lock);
{code}
which explicitly stops this situation.

What this change seems to do is that, once you stopReceiving, the channel can never start receiving again?
