jaikiran pai commented on AS7-3796:
-----------------------------------

I have a test which tries to do something similar in AS7. I had run that while implementing this solution. I'll rerun it again and send a pull request for upstream so that we have this thoroughly tested. In the meantime, I'll see if we are missing some path which might not be using the semaphore before writing out to the channel(I don't think we have missed any, but will check again).

> David and Jaikiran,
> lets revisit this topic. I still think were are leaking messages in remoting3. Badly. Even though I set MAX_O_Ms to 100K it still results in:
