commit ef2cc27cf860b79874e9fde1419dd67c3372e41c upstream
In the past, I guess the idea was to use state in order to
allow an autofush logic. However, in the current code, it is
used only for debug messages, on a poor man's solution, as
there's already a debug message to indicate when the properties
got flushed.
So, just get rid of it for good.
