Please ignore this request. As it turns out, the hangs are still there, it just takes a bit longer to trigger.

We must be leaking pages during hibernation somehow, although I cannot replicate this on my system. I think I will have to revert I/O improvements on image save for now or maybe replace then with a bit of async I/O in a separate thread to at least retain a bit of the performance gains.

Will keep you posted.
