More reverse engineering results

I've been working with the NewtonOS sampler program a bit more, and started to work a bit more on the inter-task communication. The more detailed results are on the NewtonOS Internals pages, so far one important finding is that NewtonOS is very lightweight what comes to memory management, and relies on a flat memory model with very little access restrictions. This means that memory must be allocated and deallocated with slightly different strategies than in a more conventional OS, specifically, data is shared more openly between tasks and must be kept valid as long as any task might be using it - the kernel does not create own copies of data.
