Unfortunately not. For example, Xorg+mplayer needs (30 sec refresh)..
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND
6487 root 20 0 366m 30m 5100 S 31 0.4 2:04.83 2 Xorg
4454 root 20 0 318m 28m 15m S 29 0.4 0:38.06 3 mplayer
..but gets this when a heavy kbuild is running along with them.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND
6487 root 20 0 366m 30m 5136 S 12 0.4 2:25.98 1 Xorg
5595 root 20 0 318m 28m 15m R 8 0.4 0:09.31 3 mplayer
There are 4 task groups active at this time, Xorg, mplayer, Amarok and
konsole where the kbuild is running make -j40.
