+  INSERT DELAYED
+
+  Insert delayed is distinguished from a normal insert by lock_type ==
+  TL_WRITE_DELAYED instead of TL_WRITE. It first tries to open a
+  "delayed" table (delayed_get_table()), but falls back to
+  open_and_lock_tables() on error and proceeds as normal insert then.
+
+  Opening a "delayed" table means to find a delayed insert thread that
+  has the table open already. If this fails, a new thread is created and
+  waited for to open and lock the table.
+
+  If accessing the thread succeeded, in
+  Delayed_insert::get_local_table() the table of the thread is copied
+  for local use. A copy is required because the normal insert logic
+  works on a target table, but the other threads table object must not
+  be used. The insert logic uses the record buffer to create a record.
+  And the delayed insert thread uses the record buffer to pass the
+  record to the table handler. So there must be different objects. Also
+  the copied table is not included in the lock, so that the statement
+  can proceed even if the real table cannot be accessed at this moment.
+
+  Copying a table object is not a trivial operation. Besides the TABLE
+  object there are the field pointer array, the field objects and the
+  record buffer. After copying the field objects, their pointers into
+  the record must be "moved" to point to the new record buffer.
+
+  After this setup the normal insert logic is used. Only that for
+  delayed inserts write_delayed() is called instead of write_record().
+  It inserts the rows into a queue and signals the delayed insert thread
+  instead of writing directly to the table.
+
+  The delayed insert thread awakes from the signal. It locks the table,
+  inserts the rows from the queue, unlocks the table, and waits for the
+  next signal. It does normally live until a FLUSH TABLES or SHUTDOWN.

+        zero error code (i.e. "no error"), if then second row fails, query
+        will fail on slave too and slave will stop (wrongly believing that the

+        format may be changed, that is equal to the global binlog format.
+        We test it without mutex for speed reasons (condition rarely true), and

+      sink  - result sink for the RETURNING clause
+
+  NOTE
+    Once this record will be written to table after insert trigger will
+    be invoked. If instead of inserting new record we will update old one
+    then both on update triggers will work instead. Similarly both on
+    delete triggers will be invoked if we will delete conflicting records.
+
+    Sets thd->transaction.stmt.modified_non_trans_table to TRUE if table which
+    is updated didn't have transactions.

+
+  XXX: why do we regard INSERT DELAYED into a view as an error and

+
+  TODO: The approach with using two mutexes to work with the
+  delayed thread list -- LOCK_delayed_insert and
+  LOCK_delayed_create -- is redundant, and we only need one of
+  them to protect the list.  The reason we have two locks is that
+  we do not want to block look-ups in the list while we're waiting
+  for the newly created thread to open the delayed table. However,
+  this wait itself is redundant -- we always call get_local_table
+  later on, and there wait again until the created thread acquires
+  a table lock.
+
+  As is redundant the concept of locks_in_memory, since we already
+  have another counter with similar semantics - tables_in_use,
+  both of them are devoted to counting the number of producers for
+  a given consumer (delayed insert thread), only at different
+  stages of producer-consumer relationship.
+
+  The 'status' variable in Delayed_insert is redundant
+  too, since there is already di->stacked_inserts.
