Hi Rodrigo,
Thats good news to hear that you are constantly improving memory management. Would you mind answering/commenting on a few topics related to memory management? Is it normal for Monotouch applications to have an ever growing memory footprint and (according to Instruments) never seem to drop back to the initial value, even after a forced GC? Is this effect due to fragmentation of the heap (I guess even SGen cannot prevent fragmentation 100%)? What Im also still wondering about: starting a Monotouch app shows initially 20MB of memory allocated in Instruments and pushing around a view UIViewControllers makes it grow to 30MB pretty quickly. An ObjC app only requires about 1MB. As there is not JIT runtime involved in Monotouch, what else requires so much memory compared to ObjC? Or is Instruments just wrong (but at least its relatively easy to get memory warnings, so it cannot be all wrong)?

Hi René, We're working on improving our memory management story all the time. Right now our focus is to make sgen (our new garbage collector) better fit the kind of workload of MonoTouch and Mono for Android. This means that right now we're not actively working on the new reference counting code, but be sure it will receive bug fixes if they are found or reported to us. Once those other features are done we might get back to it.

I have not read any updates about it. Is it unchanged since it was introduced or are you always working on it, enhancing it silently?
