INT 15 - TopView - SEND MESSAGE - "FREE" - FREE AN OBJECT
        AH = 12h
        BH = 02h
        BL = object
            00h handle in DWORD on top of stack
                window: close window and free
                timer: free timer
                panel: free panel object
                pointer: free pointer
            01h task's window handle - kills task, never returns
            02h given task's mailbox (task's handle on top of stack)
            03h current task's mailbox
            04h given task's keyboard (task's handle on top of stack)
            05h current task's keyboard object
Notes:  when a window is freed, its keyboard and pointer objects are freed;
          task windows also free any mailbox, objectq, and panel objects held
          by the task and any child tasks
        if the keyboard being freed is the default keyboard for a task, this
          call is equivalent to CLOSE
        panel and pointer objects are automatically closed if open
