The window for this behavior to occur is not the full resize operation, just the linking period, but it may occur. The length of the window is typically equal to a grace period. We can provide a synchronization function to block the dumper or the insertion/removal until the linking is complete. The latter would give the old runtime behaviour back (variable runtime of insert), the blocked dumper might be preferred.
