It would appear that I need help with devising a proper test.  So far,
all tests have shown no difference in performance based on the patch;
I get almost twice the speed as a single job running in one database
transaction either way.  Can someone explain what I should try to set
up to get a "best case" and a "worst case" for the patch?  Our
production databases don't expose any difference, but I'm willing to
try to use them to "seed" an artificial case which will.
