is that not what the `operation-time` cache[1] is already there to do?
(traverse x operation-done-p) reads as if module-level "done-p" is  
hard-coded[2] with logic, which is different than that for components  
in general, and which does not act on this cache. perhaps some  
protocol additions would work here.

anyway, wrt to the question on line 1265, the codes reads as if the  
answer might be that dominant operation nodes should be able to  
specify the particular particular sub-operations to force.
