I'd say "right", but I'm still wondering if "cuts in the queue" includes not only "going to the head of the line" in the queue, but also preempting a presently-running lower-priority task.

I'm also wondering how the 2010 FRC LabVIEW framework handles what I will call the "standard form" periodic tasks, i.e. like the default templates provided in the framework periodic vi. Does LabVIEW set them up with the same priority? And if so, does the OS preemptively time-slice-multitask all equal-priority tasks, or is the multitasking strictly cooperative (in the "standard form").

I say "wondering" instead of "asking" because I don't want to make it sound like I'm insisting on an answer. But if anyone does know, I'd sure be interested.
