Subject: Remove pointless sleep()
 The IM support patch from [1], imported into Mageia in [2] adds a
 conditional sleep() call when the infinite loop runs into an empty
 event queue which is bound to happen quite a few times.
 .
 This introduces pointless code and pointless wake ups as the used
 XNextEvent function blocks on an empty queue anyway [3], thus
 rendering the manual sleep() call superfluous.
