#   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.
