I don't know the history, but what is the reason for limiting a user to 2 tasks per processing core? For example, on my 4 core cruncher, I can have at most 8 tasks downloaded at any one time. Is there any chance this limit could be either increased or eliminated? At least one project I've participated in starts out with a low limit on tasks. As the user returns valid tasks the limit is increased while returning invalid tasks lowers the limit. Sorry, but I don't recall which project that is.

There shouldn't be any reason for that. Let me look into it.

Bumped the max_wus_in_progress to 4, so hopefully that should fix it.
