Hi, mariano,
Thanks for your advice, but do u think it's really good idea? The first
thing that stops me is resource leaking problem. Do u think RAM would be
completely freed in this case (without calling stop function)? And
another one, how do u suppose to change mustExit variable? U can ran
into a situation when mustExit is compared to the "true" value in run()
method and at the same time u change it (mustExit) to false from another
function. Anyway it would be great to have a look at your program (if
it's really simple and short :)) ), since i could get there some ideas
about solution of this problem.
