* draw header - rectangle with the left upper corner (1,1) and
right lower (xsize-1,min(20,ysize-1)) color indicated in esi

-2 - futex dword does not have the same value as edx
Remarks:
* This operation tests that the value at the futex dword still
* This functionn tests that the value at the futex dword still
contains the expected control value, and if so, then sleeps
waiting for a wake operation on the futex.
