Actual lite-c or c++ ? Wont hold my breath for any further more proof of "lite-c" being worth anything but paperweight , seriously you dont want to argue that lite-c is anything but half measures ?

No , if he is running that computation during the time he plays the music , doung it on another thread will help taking the extreme load off the cpu because windows will split up the time every task occupies taking the load off of his main application period , do a couple of heavy algorithms in your main app and the cpu will have to dedicate time to your app and take alot of load while splitted up into seperate threads/tasks the cpus load will be split up by the time it gives to process every task and the processing load will be taken off the main app period thats why we have multicores these things are linked and designed for a reason , you want to argue that threads were actually invented for anything less ?
