Start mining for the next hash when submitting the previous hash

[Milo123459]

Currently, when a TX is being submitted mining stops completely. If a TX reaches max retries, it will spend the remaining time of that minute trying to find a hash. It would be optimal if in the background (whilst the tx is being submitted) the next hash was being mined in the background.

makes sense, if there is no correlaction between these actions

I'm not sure this is actually possible. I think maybe until you submit a solution, you get the same challenge as before. I don't fully understand it yet though.
