Hi again, just before someone yells at me with the "No-blocking is not
magic", my point is that my test script depends from remote services or
machines that I can´t control.
It is not the case of a long and slow query to a database. If the queries
are the bottleneck and it is a permanent bottleneck, I understand that I
should try a different approach. It also happened to me using object
oriented event driven ActioScript architecture (waiting for infinite events
to come back are also a bottleneck itself).
But if it depends on a remote danger that can paralyze all my app, I think
that the "non-blocking" feature should be really a feature, somehow isn´t
it?
Am I too lost?

Nacho B
