I also think that the player process will not swap out, but other tasks can and will . See the output of top :

I also tried using nice to start the player :

I don't think it will do anything though.
Kim, do you have any more info about how the player executable is linked with the kernel.
I should think it will operate in user and in kernel mode.
Which part is embedded in kernel and which is handled by the kernel?
