+/**
+  @file include/mysql/service_thd_wait.h
+  This service provides functions for plugins and storage engines to report
+  when they are going to sleep/stall.
+  
+  SYNOPSIS
+  thd_wait_begin() - call just before a wait begins
+  thd                     Thread object
+                          Use NULL if the thd is NOT known.
+  wait_type               Type of wait
+                          1 -- short wait (e.g. for mutex)
+                          2 -- medium wait (e.g. for disk io)
+                          3 -- large wait (e.g. for locked row/table)
+  NOTES
+    This is used by the threadpool to have better knowledge of which
+    threads that currently are actively running on CPUs. When a thread
+    reports that it's going to sleep/stall, the threadpool scheduler is
+    free to start another thread in the pool most likely. The expected wait
+    time is simply an indication of how long the wait is expected to
+    become, the real wait time could be very different.
+
+  thd_wait_end() called immediately after the wait is complete
+
+  thd_wait_end() MUST be called if thd_wait_begin() was called.
+
+  Using thd_wait_...() service is optional but recommended.  Using it will
+  improve performance as the thread pool will be more active at managing the
+  thread workload.
