> Currently, each Stream has one Thread in charge of processing the incoming 
> events on the appropriate PE. If one PE blocks it's execution while 
> processing an event, the whole Stream would be blocked. The current solution 
> is for a PE to manage his own async thread, which I don't think it's nice.
> It would be better to have a configurable number of threads that would take 
> care of the execution of the incoming events.
