Independent auf pulseaudio

When running a simple app that gets a Sequencer object and exits,
OpenJDK will create the object and not exit while sun-java6-jre (version
6-07-4ubuntu2) creates the object and properly exits. The proper
behavior is the one Sun's java exhibits.

Sample program (also attached):
import javax.sound.midi.*;

public class MusicTest1 {
    public void play() {

        try {
            Sequencer sequencer = MidiSystem.getSequencer();
            System.out.println("Successfully got a sequencer");
        } catch(MidiUnavailableException ex) {
            System.out.println("Bummer");
        }
    }

    public static void main(String[] args) {
        MusicTest1 mt = new MusicTest1();
        mt.play();
        System.out.println("After play");
    }
}

The fault is in Gervill synthesizer. It created two non-daemon threads which 
prevented the VM to exit when the synthesizer was open.
And MidiSystem.getSequencer() causes the synthesizer to be open,
regardless if you don't call open() on the sequencer object. 
This has been fixed in Gervill CVS.

Updated to new Gervill CVS.

- Fix: Throw IllegalArgumentException Exception on
       invalid soundbank to:
       SoftSynthesizer.unloadAllInstruments(Soundbank soundbank)
       SoftSynthesizer.unloadInstruments(Soundbank soundbank, Patch[] patchList)
       just like done in:
       SoftSynthesizer.unloadInstrument(Instrument instrument).
- Change: SoftMainMixer, SoftVoice optimized for mono voices.
- Change: SoftFilter optimized.
- Fix: Turn SoftJitterCorrector, SoftAudioPusher threads into a daemon threads.
       These threads prevented the VM to exit when synthesizer was open.

  proper behavior is the one Sun's java exhibits.
