Yes, I think this will work as long as your environment isn't
polluted by something like $ENV (any increase in the environment size
will effect xargs's calculation of how many arguments will fit on the
command line).
Of course I still prefer the xargs fix - as you said above, it'd be
nicer in C :-)
