Description
The same as before, but in swapper.
Note, this does not bring additional actual safety, only runtime safety against exceptions. We should probably do another pass after this gets merged, and convert the naive tackling
to a more carefully thought one, which instead of just ensuring crashes don't happen, allow sub-optimal user states not to happen, either.
Issue (if applicable)
relates to #8909
Risk
Theoretically because it does bring safety. In effect, medium, touches all swapper.
Testing
Engineering
Operations
