Your app will not be paged to the disk at all. It must run entirely on in physical memory. To know when you're running out of memory, override -[UIViewController didReceiveMemoryWarning]

You typically only get about 5-40MB of available RAM. Its not flash. Its real RAM. But you have no guarantees. The iPhone has a robust memory system with low memory warnings and such and you just have to use those to determine if you have enough.
Hmm, that's kind of a harsh environment... The notification mechanism is great for the purpose of controlling bloat, but doesn't tell you how much VM you have to play with at the outset. I suppose all I can do is *try* to alloc() and if it fails, well, then what? It sounds like it's mostly out of my control if whatever else is running has already consumed VM. Gotta rethink this entire thing.
