Visible effects on FPS (max/min/avg) ?

It could be your process table lister considers each thread as a
separate process. One thread is the SDL sound consumer, one is the parser
and one is the main one. The parser is likely the 2% one, the sound the 25%
and the rest is main (VM + renderer).
NOTE: current trunk fails building statically, I hope it's going to
be fixed soon for more detailed profiling.
PS: Any progress about cleanup/port to trunk ? Need help ?
