+ Enable asynchronous teardown. A new process called "cleanup/<QEMU_PID>"
+ will be created at startup sharing the address space with the main qemu
+ process, using clone. It will wait for the main qemu process to
+ terminate completely, and then exit.
+ This allows qemu to terminate very quickly even if the guest was
+ huge, leaving the teardown of the address space to the cleanup
+ process. Since the cleanup process shares the same cgroups as the
+ main qemu process, accounting is performed correctly. This only
+ works if the cleanup process is not forcefully killed with SIGKILL
+ before the main qemu process has terminated completely.
