31   This force mysqlnd to do a single (or more depending on amount of data)
32   non-blocking read() calls before sending a command to the server. Useful
33   for debugging, if previous function hasn't consumed all the output sent
34   to it - like stmt_send_long_data() error because the data was larger that
35   max_allowed_packet_size, and COM_STMT_SEND_LONG_DATA by protocol doesn't
36   use response packets, thus letting the next command to fail miserably, if
37   the connector implementor is not aware of this deficiency. Should be off
38   on production systems, if of course measured performance degradation is not
