size of the arguments is a function of data distribution, which can
be any. Instead of overcommitting at the first row, we grow the
allocated amount by the factor of 2. This ensures that no more than
25% of memory will be overcommitted on average.

Flush (close) a list of HANDLER tables.

Scan the handler tables hash for matching tables.
SYNOPSIS
mysql_ha_flush()
thd Thread identifier.
tables The list of tables to close. If NULL,
close all HANDLER tables [marked as flushed].
mode_flags MYSQL_HA_CLOSE_FINAL finally close the table.
MYSQL_HA_REOPEN_ON_USAGE mark for reopen.
MYSQL_HA_FLUSH_ALL flush all tables, not only
those marked for flush.
is_locked If LOCK_open is locked.
@param thd Thread identifier.
@param tables The list of tables to remove.
DESCRIPTION
The list of HANDLER tables may be NULL, in which case all HANDLER
tables are closed (if MYSQL_HA_FLUSH_ALL) is set.
If 'tables' is NULL and MYSQL_HA_FLUSH_ALL is not set,
all HANDLER tables marked for flush are closed.
Broadcasts refresh for every table closed.
NOTE
Since mysql_ha_flush() is called when the base table has to be closed,
we compare real table names, not aliases. Hence, database names matter.
RETURN
0 ok
@return Pointer to head of linked list (TABLE_LIST::next_local) of matching
TABLE_LIST elements from handler_tables_hash. Otherwise, NULL if no
table was matched.
