User interrupt should very quickly stop

[percepo]

When a user interrupts the runtime, they are not interested in wenum "finishing remaining requests". They dont care anymore, otherwise they would not have interrupted. Such user interrupts should therefore simply kill open connections instead of waiting for them for up to the request-timeout of time (or plugins running for who knows how long)

[percepo]

That being said, routines such as printers being able to add their footer may still be something that should be respected, even after an interrupt has been registered
