Actually, xargs wont (shouldn't) do that.  The point of xargs is to
break up a too-long-list of arguments into more managable chunks.  If
it does have a problem, you can just use 'xargs -n 100' to limit
yourself to 100 arguments per instantiation of fs.  Tune '100' to your
heart's content.

I agree with you.  I even stated as such in my original mail.
However, it's what's available _today_.  If/when your management tool
is avaialble that will certainly be a better tool for local cell
analysis.  But it's still a pipe dream.
