Comment (by iandunn):

 It should be easy to get around that by making sure the transient key is
 unique to the data, which is a best practice anyway. Something like:

 $concatenated_data = $track_slugs . implode( ',', $speaker_ids );
 $transient_key     = 'wordcamp_speaker_ids_' . substr( md5(
 $concatenated_data ), 0, 24 ); // transient keys are limited to 45

 Truncating the MD5 hash technically opens it up to collisions, but it's
 probably rare enough that it won't be an issue in reality.
