I think that the suspend operation should spin waiting for : I/O that's in progress to complete. Yes. I hadn't thought of that. There are some wrinkles that we'll have to deal with. The APM 1.2 spec says we need to continue polling once per second while we're doing a suspend or standby operation to ensure that a critical suspend event doesn't come in. If it does, we have 5 seconds to acknowledge it (which will cause an immediate suspend if I read correctly).
