LD_ASSUME_KERNEL was an absolute usability disaster, it's not something anyone should be pointing to as justification. Threading really was not a bottleneck on most peoples systems, and it would have made much more sense for NPTL to be opt-in, instead of opt-out. The end result of stuff like this is that all the good work projects like GNOME have done gets thrown away, because the moment Joe User wants to run a cool game or their mission critical app, they have to dick about with the command line setting obscure meaningless variables that you Just Have To Know. thanks -mike
