There patch protects vmstop_requested with a lock and introduces qemu_system_vmstop_request_prepare. Together with the new call to qemu_vmstop_requested in vm_start, qemu_system_vmstop_request_prepare avoids a race where the VM could remain stopped even though the iostatus of a block device has already been set (for example). qemu_system_vmstop_request_prepare however also lets the caller thread delay observation of the state change until it has itself communicated that change to the user. This delay avoids any possibility of a wrong reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.
