INTEGER refresh()
This function checks the current frame's tick count. If it is nearly
depleted it will preempt the task (similar to pause()), resuming it with a new tick count after all other current
tasks have completed.
If the server is running atomically, the task will not preempt, and the tick count will automatically be refreshed. See Frames and Tasks for more information.
