Ah - Neworld started my list yesterday!

This list is longer (1 entry, I think), in a different order, and has different entries (ex: Melroh's World is missing).
After that I got the same list as above each time (3x - raw side by side)... this was on Mac 10.6 & FF 5.
I'll try on a PC later... but, this is tickling some feeble synapses from several years back having to do with ASP.NET and MS SQL (multiple CPUs involved in query?).
