This force mysqlnd to do a single (or more depending on ammount of data)

non-blocking read() calls before sending a command to the server. Useful

for debugging, if previous function hasn't consumed all the output sent
|
|
to it - like stmt_send_long_data() error because the data was larger that
|
|
max_allowed_packet_size, and COM_STMT_SEND_LONG_DATA by protocol doesn't
|

use response packets, thus letting the next command to fail miserably, if
|

the connector implementor is not aware of this deficiency. Should be off

on production systems, if of course measured performance degradation is not

minimal.
