I just realized that the unifying framework for countermeasures of any 
resource based attacks (time, electricity, heat, radiation) is MaxEnt. 
Constant time is trivially MaxEnt. If you can't do constant time, go for 
uniform distribution over a number of predefined times. If you can't do 
that, from the space of possible distributions, choose the one with 
maximum entropy. So much for the theory.

E.T. Jaynes would be delighted to see his work appear in yet another
