Comment (by leewillis77):

 As with #19690, the use case that caused me to stumble on this is in
 plugins that wish to iterate over all (or a potentially large number of)
 posts. The specific use case that caused this is generating an XML feed of
 product information from e-Commerce stores for Google Merchant Centre.

 In this context you want to iterate over all posts of a specific type, but
 there's no specific advantage in adding those posts (Or related
 information) to the cache - hence the use of
 wp_suspend_cache_addition(true).

 Unfortunately as soon as cache additions are suspended, get_post_custom
 fails to return data for posts that do have custom info set.
