Hard to say what is going wrong but the solution is simple. Whenever
you have a resource that must be released, do it explicitly. The way
this is usually implemented is either:

  f =3D File.open 'foo'
  puts f.read
  f.close

Or, more conveniently

  File.open('foo') {|f| puts f.read}

The block-form uses ensure to make sure the file handle gets closed.
