This will help to avoid the very high latencies that thin stream su= ffer because of exponential backoff. This mechanism is only active if e= nabled by iocontrol or syscontrol and the stream is identified as thin. >=20 Wont this reduce the session timeout to something very small, ie 15 ret= ransmits, way under the minute ?
