# is not clear

yes, when class is first loaded or redefined.
# an instance is created, ???
no, otherwise it gets executed many times per instance (assumming of course you just want it to run once :) You can use initialize() if you want something invoked per instance-iation.
btw, you can monitor behavior using irb and debug. but in case you doubt if they do some magic, you can also do tracing. try putting the ff code at the beginning of the program you want to observe,
#----
set_trace_func proc do |event, file, line, id, binding, classname|
printf "%8s %s:%2d%10s %8s\n", event, file, line, id, classname
end
#----
ruby is really very open. have fun.
