rt_task_create may reschedule the calling task, only "may", not "should". And it happens in the obvious case: when creating a task with a higher priority than the current task. The reason why rt_task_delete may reschedule is documented: "Native tasks implement a mechanism by which they are immune from deletion by other tasks while they run into a deemed safe section of code. This feature is used internally by the native skin in order to prevent tasks from being deleted in the middle of a critical section, without resorting to interrupt masking when the latter is not an option. For this reason, the caller of rt_task_delete() might be blocked and a rescheduling take place, waiting for the target task to exit such critical section."
