We have several options:
1. No memory overcommit feature. This is always the case ATM!
2. Do not hot-plug assigned device.
3. Hot-unplug assigned device.
4. Some assigned devices can be able to handle memory errors
   e.g. using ATS. Limit hotplug to these.

OK, let's leave it alone, and the first person to try to implement it in
a device can figure out how to fall back.

I replied on the other thread: I think a SILENT_DEFLATE option is
a future optimization.
