Another point to consider here is the ease of multi-threaded programming in Coldfusion. If you have ever tried to pull this off in other languages you know what I mean. CF is naturally multi-threaded out of the box, this saves you from manually coding in all the hard stuff; instead you just use shared locks, or exclusive locks on variables that may be the target of races conditions. CF7 is good as doing this for you if you forget; but I'd use locks always just to be safe. Bottom line is threading is tough, and threading well is REALLY tough; but with CF it is as easy as a CFLOCK tag. Can't beat it.
