Please, as Peter and Boris asked you already, quote a concrete, specific 
example:

  'Specific event X occurs, kernel wants/needs to do Y. This cannot be done
   via the suggested method due to Z.'

Your generic arguments look wrong (to the extent they are specified) and it 
makes it much easier and faster to address your points if you dont blur them 
by vagaries.

Thanks,
