It happens with earlier 2.4.x kernels too. It may be easier to trigger now (although the data doesn't actually seem to support that very much either). Regardless of any lazy movements or anything else, the VM should always make progress. When you claim that reclaimd gets "effectively disabled" but the current setup, then explain how it couldn't have happened without lazy movement. Lazy movement may give non-optimal heuristics, but if the heuristics sometimes say "don't make progress", then those things could have happened without the lazy code - by having the _real_ conditions match the ones that the lazy one happened to be.
