Which the top-level can't possibly solve except by using
.NOTPARALLEL. Remember that configure doesn't get run only when you a
sub-directory hasn't been configured yet, but also when it has to be
reconfigured, and in this case, the top-level has already handed
control down to the sub-directory. So, the only way to guarantee
consistency is to set .NOTPARALLEL.
But then, I was against the whole thing of enforcing consistency by
default, so I won't get in the way if you want to lift at least part
of it now :-)
