Need to handle themes with multiple 'the_content' areas

[goldenapples]

Themes which call 'the_content' filter multiple times on a page cause the list of links to be displayed multiple times on the page set as "Page for Recommended Links Archive". Need a way to determine which is the primary content area and ignore the others.

Note: this is different than secondary loops, which are already being handled. This problem appears to be specific to themes which allow users to define multiple content blocks within a single page.
