* Close the hanging TCP message channels after a dynamically aligned timeout (base `10000` milliseconds) * Bring back `source.Lazy` * Add a one more `sync.Map.Delete` call * Improve the formula by taking base Goroutine count into account * Reduce duplication * Include the dropped TCP streams count into the stats tracker and print a debug log whenever it happens * Add `superIdentifier` field to `tcpStream` to check if it has identified Also stop the other protocol dissectors if a TCP stream identified by a protocol. * Take one step forward in fixing the channel closing issue (WIP) Add `sync.Mutex` to `tcpReader` and make the loops reference based. * Fix the channel closing issue * Improve the accuracy of the formula, log better and multiply `baseStreamChannelTimeoutMs` by 100 * Remove `fmt.Printf` * Replace `runtime.Gosched()` with `time.Sleep(1 * time.Millisecond)` * Close the channels of other protocols in case of an identification * Simplify the logic * Replace the formula with hard timeout 5000 milliseconds and 4000 maximum number of Goroutines
