free() for the slave thread. Indeed, doing a x_free() on it leads to nasty
problems (i.e. long painful debugging) because in this thread, thd->db is

pointers which point to the same place). Then in ~Query_log_event(), we
have 'if (data_buf) free(data_buf)' data_buf is !=0 so this makes a
DOUBLE free().
Side effects of this double free() are, randomly (depends on the machine),

Change default database.
Change the current database.
SYNOPSIS
mysql_change_db()
thd Thread handler
name Databasename
no_access_check True don't do access check. In this case name may be ""
thd thread handle
name database name
no_access_check if TRUE, don't do access check. In this
case name may be ""
DESCRIPTION
Becasue the database name may have been given directly from the
communication packet (in case of 'connect' or 'COM_INIT_DB')
we have to do end space removal in this function.
Check that the database name corresponds to a valid and
existent database, check access rights (unless called with
no_access_check), and set the current database. This function
is called to change the current database upon user request
(COM_CHANGE_DB command) or temporarily, to execute a stored
routine.
NOTES
Do as little as possible in this function, as it is not called for the
replication slave SQL thread (for that thread, setting of thd->db is done
in ::exec_event() methods of log_event.cc).
This function is not the only way to switch the database that
is currently employed. When the replication slave thread
switches the database before executing a query, it calls
thd->set_db directly. However, if the query, in turn, uses
a stored routine, the stored routine will use this function,
even if it's run on the slave.
This function does not send anything, including error messages to the
client, if that should be sent to the client, call net_send_error after
this function.
This function allocates the name of the database on the system
heap: this is necessary to be able to uniformly change the
database from any module of the server. Up to 5.0 different
modules were using different memory to store the name of the
database, and this led to memory corruption: a stack pointer
set by Stored Procedures was used by replication after the
stack address was long gone.
This function does not send anything, including error
messages, to the client. If that should be sent to the client,
call net_send_error after this function.
