A little bump on this thread.. I have now, after a month and two processed films in the same 350ml working solution. seen a bit of white slush, or whatever it could be called, in the bottom of the little more than half full bottle containing the developer, stored in room temp. As i wrote earlier, i am pushing things a bit just to test. Some day next week i will try to process a roll of Reala in it for 8min at 30C. If this also comes out OK i am going to be close to say that this will be my choice of C41 developer in the future.
