It is *non*-deterministic. The decision to reallocate depends

The LRU is thread local.
It will then prevent a moving GC from being possible in D.
Otherwise, moving a block of data will invalidate LRU which will
result in non-deterministic reallocation.
It won't work with the existing GC either. If a page is completely
emptied then it can be re-used for different sized allocations. This
is why the current cache is wiped during a collection.
In both cases, the LRU can be adjusted rather than wiped to account for it.
