As part of the TCPConnection/EPoll One Shot changes that I previously submitted, there was a bug where when the TCPConnection experiences throttling, it won't ever get notified when we are ready to send again. This patch addresses that in the short term. There's a PR coming from Dipin Hora that addresses this in a better fashion and handles a subtle race condition in One Shot ASIO events. This small patch should suffice in the meantime and get master back to a correct state.

Would be nice if we had some tests that covered this, but I believe it was discussed in #1539 that it wouldn't be practical. |

@jemc i think what we need are Spy type tests that verify the contract is working correctly. We are lacking a bit on tooling for that at the moment. I started a discussion with Sylvan over the weekend on what would be required to write a nice spy tool for Pony. |
