This function should be called when MySQL sends rows of a SELECT result set
or the EOF mark to the client. It releases a possible adaptive hash index
S-latch held by thd in InnoDB and also releases a possible InnoDB query
FIFO ticket to enter InnoDB. To save CPU time, InnoDB allows a thd to
keep them over several calls of the InnoDB handler interface when a join
is executed. But when we let the control to pass to the client they have
to be released because if the application program uses mysql_use_result(),
it may deadlock on the S-latch if the application on another connection
performs another SQL query. In MySQL-4.1 this is even more important because
there a connection can have several SELECT queries open at the same time.
