The test verifies that delayed fibers are started in the right order, and that cancelling delayed fibers recomputes correctly the timeouts in the queue. Also test the fiber_sleep() API. Change-Id: Ic3169a90b434a81c96e7c5d3c74c39431c988f39 Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>
