SoundPlayer has still room for improvement

Not sure whether this is a real issue, maybe just an observation:

AbstractSound stereoBachFugue play

At least on Chrome/Windows with a Squeak6.0 Alpha 64-bit image, the sounds plays all but not fluently. Nevertheless, the overall performance improvements since I have used SqueakJS the last time are very notable! :-)

Something that I would consider worse than the performance is that I was not able to interrupt the image from playing the sound by using Cmd + Dot. The debugger just did not appear. IMO interrupts should always be possible but apparently, the VM was overcharged with primitive calls and had no time to let the interrupt handler run. Could this be changed or is this a limitation by design? :-)
