Using sleep in this way does not make sense at all.

  - Any GUI action (i.e. displaying changes) is blocked while the main 
is sleeping.
  - the GUI actions are performed by events and can will be performed at 
"some reasonable point in time" after the action is scheduled by the 
user program.

The purpose of sleep() is nothing but "allowing for other threads and 
processes to use the CPU for at least the given milliseconds".
