Ah, I have an idea! We should anaylze a native Linux SDL program
running versus the same exact program compiled for Win32.

If the program is written well enough, it should not cause delay in
its own code. This way if wine takes considerable amount more time
running the audio threads than it would using direct native code, we
can try to take a hard look and improve Wine's sound to act the same
as the linux native version as much as possible.
