It's less of a problem that one queue-item does not get handled, attention wise,
than that the queue keeps filling up. The typical error raised here is 'already exists'
so it's not even the case that the item won't get handled (it already has been).
The real problem is that the queue_item table accepts duplicates (content-wise) which it
should not.
Added the following FIXME:
How should a Twitter user get their Inbox filled with foreign tweets?
Every imported Twitter user has a profile in the Profile table, so we
could setup a Subscription entry for each of those, meaning they get
collected in the InboxNoticeStream... But this would mean a lot of
unnecessary entries and listings that generally just point to the
locked down Twitter service.
Let's figure out a good relation so we can connect any profile to any
imported foreign notice, so it shows up in the "all" feed.
lib/plugin.php now has a parent onAutoload function that finds most common
files that are used in plugins (actions, dataobjects, forms, libs etc.) if
they are put in the standardised directories ('actions', 'classes', 'forms',
'lib' and perhaps some others in the future).
