+      # the x seconds. In a normal case this would be a timeout on wait/read, but it can
+      # also mean that the socket has been closed by the server. Therefore we "mark" the
+      # socket for timeout and try to read more bytes. If it returns :eof, it's all good, no
+      # timeout. Else, the first timeout was a proper timeout.
+      # This hack has to be done because io/wait#wait_readable doesn't provide a value for when
