With lots of devices (one qcow2, 23 raw scsi disks)
I get a hang on shutdown. kvm_stat claims that nothing is going on any more,
but somehow threads are stuck in ppoll.
gdb tells me that

How are the ppoll calls supposed to return if there is nothing going on?
PS: I think I have seen this before recently during managedsave, so it might
have been introduced with the iothread rework instead of this one.
