Is called when feed engine's thread is idle.
Thread becomes idle when either no data is received within time interval defined by FeedEngineSettings::dataWaitTime parameter or no pending data is available for processing. In the first case, callback is invoked with 'DataWaitTimeout' reason. In the second case, thread is considered as redundant and thus callback is invoked with 'Redundant' reason. After callback invocation threads may sleep in kernel to reduce load onto CPU and racing between feed engine working threads.
Integer parameter-variable defines amount of time feed engine suggest for thread to sleep in kernel after invoking given member.
