Then simple launch sys_sync(), let it finish, *then* do
refrigeration. That way sys_sync() does not count to the timelimit.

Now, sys_sync() takes too long on some setups. That needs to be fixed,
anyway; users don't like to wait for 15 minutes after typing
"sync". Do not work around it in refrigerator.
