Now I am working with rev. 1.113 and I faced some performance degradation.
Sound from xmms trembles when I start xterm or open a new TAB in mozilla,
unless I give a real time priority to xmms. No CPU consumers are working at
this moment, LA is 0.

Yesterday I was working on a buggy revision of 1.113, but compiled without
'#define PREEMPTION'. There were no performance problems.
