I have a lot of Pending WU's from back in Dec of 2010.
Are these just lost work?

Not lost, still pending. Most pendings clear within a few days to a week when the wingman completes the task. Some people stop processing Collatz tasks and detach without first aborting the tasks still in their cache or abort them after 14 days. Either way this means that after 14 days those tasks are then reissued and so begin another potential 14 day cycle. In my experience only a very small percentage of tasks remain pending after 2 full cycles or 28 days. This kind of thing happens in all projects that have a quorum and a longish report deadline. Some CPU only projects with a similar report deadline have a much higher percentage of tasks that stay pending for more than one cycle.

Sometimes after there has been some downtime in a project , there can be an increase in the amount of pending because some who have switched to another project during the downtime just report those tasks they have completed when the project server is running again and then detach from the project without first aborting unfinished tasks in their cache.

If you click on the number in the "Work Unit" column in any of the Pending lists (best to go for the individual PC(s) screen at the moment - the global pending screen is broken ) you will see the WU History and latest action. The latter shows the reason a WU failed, and when the latest attempt started to get it crunched by another Cruncher.
