Jeez. Don't mentione the desktop. On the desktop this is compleltely
irrelevant. There are not TTYs on the desktop. There's no "make -j" of
the kernel tree on the desktop.

The kernel patch discussed here *has* *no* *relevance* for normal users.

The kernel patch discussed here is only relevant for people which start
mplayer from one terminal, and "make -j" from another.
