 Working with `bp_get_user_groups()` on a site where a user is a member of
 many hundreds of groups, I've noted some performance issues.

 First: when looping through groups and casting keys to integer or boolean,
 the key whitelist is being regenerated each time through the loop. This
 only needs to be done once.

 Second: `wp_list_filter()` is slow. I wonder if there's a way to filter
 these items earlier.
