v2.20.04b2

• #320 another improvement in error recovery. better results on flakey_flow
• #319 remove pulse, causes more harm than benefit, perhaps re-introduce after better testing.
• connection recovery: remove recursion (vulnerable to stack exhaustion on long failures.)
• connection recovery: add exponential backoff to several failure modes.
• remove channel close logic (unnecessary, as entire connection is closed, which closes all channels.)
