I believe ICANN received 37 reports of problems with name collisions, all of which (to my knowledge) were dealt with by putting the impacted party together with the registry in which the name collision occurred.
Some quick searches show there are also reports like:
that do not appear to have reached ICANN directly.

Name collision is, of course, NOT limited to top-level domains.

Not really. It appears to have done precisely as intended in the cases mentioned above.

Controlled interruption was never intended to prevent collisions, rather it was to provide bread crumbs for folks who encountered difficulties to help them find where they were leaking queries so they could fix those leaks. It is, of course, impossible to know how well it worked (or not) since it's likely most system administrators who ran into the problem went and fixed it without bothering to tell anyone.
