Subject: Clean way of pausing a loop?

It's Monday and it's relatively early, so I apologize if this isn't
worded too well.

Is there a clean way of pausing a loop/printing status every N
iterations?  I often use ruby to examine log files in a one-off
fashion, and when dealing with files of 4-10 million lines, this is
the sort of thing that becomes important.  Small files are, obviously,
not as big of a deal.

I know I can simply do this, but it doesn't seem clean:

counter=0
n=100
foo.each do
|bar|
   counter+=1
   if (counter%n).zero?
     sleep 0.1
  end

Thanks,
       Kyle
