I've got a use case for this: I went to one of the Graphene talks in
Edinburgh and it struck me that we seem to keep reinventing the type of
sandboxing that qemu-user already does. However if you want to do an
x86 on x86 sandbox, you can't currently use the binfmt_misc mechanism
because that has you running *every* binary on the system emulated.
Doing it per user namespace fixes this problem and allows us to at
least cut down on all the pointless duplication.
