(2) For the first few minutes of COMM, there were some telemetry hits.
DSS-54 and OC reconfigured and got steady telemetry, but in the process
it killed the recv_tlm on coot and messed up all associated processes.
Snap was a little funny for several snapshots and now appears to be
frozen at 666 (ironic).  All disp processes on coot were restarted.
