According to xmms sources, it uses 250ms fifo; which means xmms eats around 250ms to scroll... that's a lot of cycles to scroll (spinning? blocking in X libs? disk i/o?). Fixing xmms to use less than 250ms or cranking the audio fifo size should solve the skipping. And this is not specific to xmms, I'm sure pleinty of other software uses kernel threads on linux to overcome similar problems. And, yes, rthreads will make such software work on openbsd as well. -- Alexandre
