It won't be horrible. You have to recreate all the processes (and getting
their address spaces mapped correctly should be easy) and get them all
ptraced by the tracing thread. UML processes which are CLONE_VM are also
CLONE_VM on the host, so that will take a little bit of care.
Devices will need to be reopened as well.
