Do you mean that the D2 GC API needs to grow something to tell that a less important memory block (object, array) can be deallocated by the GC in low memory conditions? How can this work in the user code?
(And it can be positive to define a standard way the D GC talks with the virtual memory subsystem of the operationg system, to avoid useless swaps from and to disk).
