# Code snippet in question
count = 1
files = Array.new
loop do
  print count.to_s + "\n"
  files << File.new("test#{count}.tmp", "w")
  count += 1
end

What you're doing here is pushing the file _descriptor_ onto the
'files' array, not the file name, and you're never closing the
descriptor. Simply increasing the descriptor limit isn't going to cut
it.

I'm not exactly sure what you're trying to accomplish, since I don't
know if you need to write to those files at some later point or what,
but you'll need to change your approach.

Also, the 'tempfile' library may be of some interest to you. It's part
of the standard library.
