As a first step I'd suggest to create a superset of all existing 
and relied-upon wrappers/callbacks, into a single obvious 
sched_*() or time_*() namespace, without breaking functionality.

Once that is done we can eliminate individual, conceptually 
redundant callbacks, by carefully morphing the affected arches 
step by step.

No arch will be left behind.
