It wouldn't; but I'm trying to better understand the problem the OP is
trying to solve, to see where that leads.
My first reaction on hearing the request was that it might have *some*
use; but in trying to recall any restart where it is what I would have
wanted, I come up dry.  I haven't even really come up with a good
hypothetical use case.  But I get the feeling the OP has had some
problem this is attempting to address.  I'm just not clear what that
is.
