I think that two different markets exist for this computer: 1. Joe user who has never seen a command line interface. These people need a nice, cozy little user environment that takes as little understanding as possible to use. They also buy the most computers and are probably most responsive to fluffy advertising campaigns. Hence the targeted advertising on apple.com In this case, my guess is that memory allocation, etc, is left to the application. For cocoa apps it is the objective c runtime handling this kind of thing and for carbon apps, it is probobably tacked on during the process of carbonizing. But I should say that I really don't know much about the low level workings of either. 2. Scientists/Engineers/Programmer types. These people configure their own limits instinctively and probably forgot that they ever put that unlimit in their rc files (like I did) and the dozens of other customizations they did to get their OS X boxes just so for unix use. When Joe User makes the crossover, such customizations don't seem very intuitive. Plus, I remember having to ulimit my IRIX account on SGIs I used back in the day--so other *nixes seem to have similar requirements. To answer your question, my guess is that no one has complained yet.
