|Yes.  It's similar to my proposal except using a particular

[ruby-talk:28803]? I don't think so.  Your patch scans filename
strings.  It's complete, but slow.  Christensen's proposal is
cheaper.  But I'm not sure if it's effective enough.  For example, it
does not prevent leaks like:

  loop {|i|
    fn = format("/tmp/%d.rb", i)
    f = open(fn, "w")
    load fn
    File.unlink fn
  }

I think [ruby-talk:28803] works well for this case too.
