feeds_entity_load() called too often / is not cached.

When showing a rather complex node, I find that feeds_entity_load() is called a lot of times. Below is a list of a node with 5 Terms and 1 countries-field.
The function adds the field feeds_nid to the entity. I am not sure what the function is of this field. I suppose it is only needed when importers are attached to the Node View page.

Anyway, there should be a smarter way to do this:
- either load/save this field together with the entity,
- or load only on affected pages, and only for the 'main' enitty.

Perhaps this issue is related: #1424992: Add implementation of hook_entity_info_alter() so that $node->feed_nid is available to Rules
