SessionPool readTimeout works incorrecly

When i specify readTimeout to Session.pool, pool cannot reuse session.

1. Create pool with readTimeout = 10 seconds
2. Make request. Wait more than timeout in my case is 3 minutes.
3. Make another request
   In debug i see this:

2021-02-18T12:17:24.835363+00:00 app[web.1]: → Query(BEGIN
2021-02-18T12:17:24.835365+00:00 app[web.1]: ISOLATION LEVEL SERIALIZABLE
2021-02-18T12:17:24.835369+00:00 app[web.1]: READ WRITE)
2021-02-18T12:17:24.835820+00:00 app[web.1]: TLS: wrap result: Status = OK HandshakeStatus = NOT_HANDSHAKING
2021-02-18T12:17:24.835821+00:00 app[web.1]: bytesConsumed = 87 bytesProduced = 116 sequenceNumber = 213
2021-02-18T12:17:24.839988+00:00 app[web.1]: → Query(UNLISTEN *)
2021-02-18T12:17:24.840394+00:00 app[web.1]: TLS: wrap result: Status = OK HandshakeStatus = NOT_HANDSHAKING
2021-02-18T12:17:24.840394+00:00 app[web.1]: bytesConsumed = 16 bytesProduced = 45 sequenceNumber = 214

If drop readTimeout - everything seams to work correctly. But how can i detect network failures in this case?

Start by reproducing the reported Session.pool behavior with readTimeout set to 10 seconds: make one request, wait longer than the timeout, then make another request. Trace how the pool handles the timed-out session and define done as successfully reusing sessions while still detecting network failures.
