+  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

+  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.
