Would you please elaborate on this? What exactly was the bug?

Can you give a couple of examples of 2010 FRC breakaway functionality which would require (or even benefit from) changing task priority?

In the 2010 FRC LabVIEW framework, all user-created periodic tasks have the same priority, and they are preemptively time-slice multitasked by the O/S. Running these periodic tasks at a reasonable rate, as you suggested, frees up the CPU so that it should have enough throughput to service all the tasks you need, no?
