>Description:
While xmms was started, I typed ps aux in a terminal window and
noticed this line:
USER   PID %CPU %MEM   VSZ   RSS TTY   STAT STARTED    TIME COMMAND
...
pavel 1326  0.0  2.1  6344 12104 ?     Rxsa 11:22PM 2:35.55 xmms
                                        ^
ps(1) says that 'x' means "The process is running under
systrace(1)". But I never used systrace... what's happening here?

I saw the galeon process doing this too. (Both xmms and galeon use SA.)
