Summary:A software thread is dispatched for causing the system to poll a device for determining whether a condition has occurred. Subsequently, the software thread is undispatched and, in response thereto, an interrupt is enabled on the device, so that the device is enabled to generate the interrupt in response to an occurrence of the condition, and so that the system ceases polling the device for determining whether the condition has occurred. Eventually, the software thread is redispatched and, in response thereto, the interrupt is disabled on the device, so that the system resumes polling the device for determining whether the condition has occurred.
