The system just responded better that way." Obviously the system being described is not a HARD real time system, where HARD refers to the predictability of the response times. "Real time" is unfortunately a haeavily overloaded concept these days. Hard real time garbage collection is still something of a research topic. "Soft" real time systems, i.e., those which are "fast enough", can certainly use GC; Ericsson, the Swedish telecommunications company, has been using the functional programming language Erlang to program telecom systems.
