+#   Profiling is a descriptive look into the way the server operated
+#   in retrospect.  Chad doesn't think it's wise to include the result
+#   log, as this creates a proscriptive specification about how the 
+#   server should work in the future -- or it forces everyone who 
+#   changes the server significantly to record the test results again,
+#   and that violates the spirit of our tests.  Please don't include
+#   execution-specific data here, as in all of the "show profile" and
+#   information_schema.profiling results.
