This is a race that can happen when migrating TCG guests under load.
It was introduced by the change to run vCPUs outside the big QEMU lock.

Paolo Bonzini (4):
  memory: remove memory_region_test_and_clear_dirty
  memory: hide memory_region_sync_dirty_bitmap behind
    DirtyBitmapSnapshot
  memory: introduce memory_global_after_dirty_log_sync
  memory: unify loops to sync dirty log bitmap
