But the patch was a bugfix and the race was between

$class = $class == 'even' ? 'odd' : 'even'

$class = $flip[$class];

Because the key is not reliable, so we must flip the class.

Yes, in that particular patch, the if-test would sometimes break (depending on the input data). The patch fixed a bug, and the tiny performance improvement was just a secondary effect. -- Dries Buytaert :: http://www.buytaert.net/
