@kYc0o Have you even looked at my code? That's exactly what it does....

The problem is every simple: The Context Swap interrupt works great, but blocks all other pins on that port from being used as a pin change interrupt, which in our case is a problem because we only have very few pins that are not used on our sensor node. I just would like to start a discussion about this and document it in this pull request / issue that this still is a big problem.
Therefore I'd like to discuss quickly if we should re-design the context swap to be able to use pin change interrupts on other pins too, but be able to have a context switch here!
