The bug is in the X SYNC extension which is heavily used by PowerDevil (and
rsibreak).   An alarm set by KIdleTime's SYNC backend is not cleared after a
suspend (or other cases, not entirely clear here) and then fires repeatedly on
the next idle.  I will check the SYNC backend to make sure it is not doing
anything wrong or odd to trigger the Xorg bug.
