one common pattern i've noticed is bug dependency. In some areas we need to fix a series of 2-3 increasingly less trivial bugs to get enough test exposure, tester confidence and developer attention to trigger (and fix) the _truly_ bad bugs.
That's why agressive regression elimination (and prevention) is so important IMHO - trivial regressions can totally block testing of certain areas of code, and with an agressive 90 days release schedule every day counts.
