Exactly. Rails, which is built on top of Ruby, doesn't allow arbitrary input as integer keys on Arrays, nor does it allow the user to force-execute a (very) long while loop.
The vectors for attacking this vulnerability in Rails is limited to incoming params or POST bodies, and so far nobody has been able to show a vector for using these vulnerabilities to execute remote code or cause a DoS attack on Rails or Merb.
