My own guess is that it will be best to have a possibly specialist
function to allocate the object, but to give it a single GEM handle. For
the most part its a list of pinned pages somewhere and while picking the
pages to use is special I am thinking that the rest of the behaviour is
probably not.

It also then means on the client side that it's a single buffer, a single
mmap and can be wrapped easily in things like libkms.
