Event Scheduling in Twisted?

The callLaters would fire in the order that you registered them. The packet arrival could fire before or after the callLaters depending on the point of execution in the event loop when the packet arrives.

There is no definitive rule here. Different reactors may implement different strategies. In general these implementations are somewhat ad-hoc and not particularly well designed, but there isn't a lot of motivation to fix them, because most applications with deep ordering dependencies on different event sources are actually just buggy, and should be fixed not to care what order these fundamentally non-deterministic events arrive in.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
