cf171ff52555b9e984a3b9103287f6b897dc8626 Close Regression

Browse Source 
Motivation:
cf171ff52555b9e984a3b9103287f6b897dc8626 introduced a change in behavior when dealing with closing channel in the read loop. This changed behavior may use stale state to determine if a channel should be shutdown and may be incorrect.

Modifications:
- Revert the usage of potentially stale state

Result:
Closing a channel in the read loop is based upon current state instead of potentially stale state.
