FreeHAL is getting low on work and every now and then is issueing this message:

29-01-2012 12:11:22 | FreeHAL@home | Sending scheduler request: To report completed tasks.
29-01-2012 12:11:22 | FreeHAL@home | Reporting 4 completed tasks, requesting new tasks for CPU
29-01-2012 12:11:37 | FreeHAL@home | Scheduler request completed: got 0 new tasks
29-01-2012 12:11:37 | FreeHAL@home | Not sending work - we don't have that much work now
29-01-2012 12:11:37 | FreeHAL@home | the FreeHAL team wishes you a Merry Christmas

With patience (and some manual effort sometimes) the WUs will come loose eventually
