like move_internal.rb, but does not loop, just finds the first few and quits immediately. it needs to be fast so that it moves things before reduce workers can pick them up.

move_small.rb

# this assumes the rails console has preloaded the resources; accordingly,
# you should invoke this script as
#
# rails c < move_small.rb
