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.
