Addresses #2420
I have a theory that concurrent calls to
ConnectTransportAsynccould put a subchannel in a bad state. Two connection requests happen simultaneously but a race condition occurs as they exit.Before:
This PR limits access to connect with a semaphore. A subchannel will have one connect in progress at a time.
After:
Note: New test is unrelated to this exact problem. I wrote it while considering another theory. It's a good test to keep around.
