It sounds rather similar to Martin's proposal, except with different
coefficients and slightly different definitions (but the "total number
of traceable objects" should be roughly equal to the number of objects
in the oldest generation, and the "number of pending trace operations"
roughly equal to the number of survivor objects after a collection of
the middle generation).
Am I missing something?
