 // Some general thoughts about the waveOut API which is badly documented :
 // - We use CALLBACK_EVENT mode in which XP signals events such as buffer
 //   releases.
 // - We use RegisterWaitForSingleObject() so one of threads in thread pool
 //   automatically calls our callback that feeds more data to Windows.
 // - Windows does not provide a way to query if the device is playing or paused
 //   thus it forces you to maintain state, which naturally is not exactly
 //   synchronized to the actual device state.
 
 // Sixty four MB is the maximum buffer size per AudioOutputStream.
