This happened initially during session load. The GUI thread performed a direct refill (blocking wait) `Session::post_engine_init() -> Track::seek() -> DiskReader::seek() -> DiskReader::do_refill_with_alloc()` while concurrently the butler thread does the same: ``` Session::butler_transport_work() -> Track::non_realtime_locate() -> Route::non_realtime_locate() -> DiskIOProcessor::non_realtime_locate() -> DiskReader::seek() -> DiskReader::do_refill_with_alloc() -> DiskReader::refill_audio() ``` We do not want the GUI to wait, so now we just request a locate and let refill happen in the background.
