 The problem still persists but is a lot harder to reproduce now.
 I can no longer reproduce with the keyboard.
 
 Moving the mouse during disk io the mouse pointer suddenly "hangs"
 for a very short moment. It happens when top shows
 the ioflush kernel thread causing cpu load and more than 5% in interrupts.
 
 I think this might be even more noticable with applications that
 rely on having a responsive system like watching a movie.
