Not necessarily... slowdowns can happen suddenly if there is a big change to the data being used... for example when a map is exchanged providing substantially more information.
I still suspect that there may be a minor memory leak (since people could often play an extra few turns after reloading a save), but it does sound likely that the main issue was simply that the system was using the memory inefficiently.
Personally, I am totally bummed because my wife said about an hour ago that she is not getting me the laptop I was hoping for and so I suspect that it will be a few years before I can actually play the game... I knew the patch info would be out as a result !
Yes, I am thoroughly whipped. <sigh>
