You can only prefetch one "direction" of has_many rels at once. Anything else
results in a cross-product return of records which tends to be heinously
inefficient anyway.
i.e.
[ 'hm_rel', 'other_hm_rel' ] won't work
although
[ { 'hm_rel' => { 'belongs_to_rel' => 'ya_hm_rel' }, 'other_belongs_to_rel' ]
and similar are fine.
