Reproduce:
Create 1001 users.
Go to Users tab.

The reason this is happening has 2 parts:
1. The data for the new list tag on that page is elaborated all at once.
2. The way we elaborate data is by putting it all into a single query with a
list of ids.....   oracle doesn't allow that list to exceed 1000 items ( The IN
limit).

We can't just cause the list to page correctly, becuase the list has sortable
columns. Those need to access every member of the list at once.
