These are very useful in many packages containing relatively large amount of code making calls to difficult or impossible to stub functions.

This used to be entirely done via integration tests, with almost no hope of error injection and coverage profile. These tests significantly increase confidence of future work in this area.

Scheduler nondeterminism cannot be accounted for, so do this instead.
There should not be any performance penalty as these calls are optimised out for direct.

This allows tests to stub all kernel behaviour, enabling measurement of all function call arguments and error injection.
