hum...
I don't now if this aproach work on my application...
I download many html pages in a specific order, one after one...
They are different html, that depends on the results of the last.
Of course that will work... But I think that use timeout to determine if
I need to restart is more simple... I'll try the firs option...
But I'll think in a way to use this... The problem is that I need
"extreme" velocity, and I don't know if work with events is a good idea
in this case...
Anyway, much thanks! =D
