Here is another old thread dedicated to it.

On the CRIO, they are called tasks. I am not sure how to use them yet myself. That part of the WPI manual is blanked out. Look at the tasks.h file in the WPILib folder. It helps a little. Also look at the camera examples in WindRiver. I believe they are using seperate tasks for image aquisition.
hope this helps a little
