If one adds a module multiple times, (in this case, the silly user just commented out the ClearModuleList) there is no warning whatsoever, yet it causes (obviously) no end of chaos and unpredictable failures. This especially impacts upgraders who foolishly copy configs from one install to another.
If someone wants a little hack to write, take the LoadModule (and on 1.3, AddModule) and actually _test_ to see if that module is yet loaded :) Bill
