Fix random panics during autoballonning. #17

There is a race condition, when good behaving VMs will temporarily truncate .memory_used to 0 bytes (update is not atomic).

Also, as a matter of principle, VMs should not crash the host, ever.

[x] I tested it locally.
[x] I tried to run at least one application VM and it works.
[x] This checkboxes are not 100% relevant but yeah, I've reproduced both the problem and the fix.

Yeah, about the signing issue... Due to the coronavirus situation I'm stuck here without my primary laptop (with my GPG key). If everything goes right, I'll have it in 2 weeks.
