5.5.4, 6.0.1, 6.5.0
The code introduced as part of following commits can cause projector to panic due to race condition on feed cleanup.
During cleanup, the genServer sets feed.conn=nil, while the doReceive can still try to access this.
As the above commits were backported to 5.5.4 and 6.0.1, the fix will also need to be backported.
