Comment (by boonebgorges):

 If you're experiencing memory issues with this `in_array()` check, it
 suggests that you have a very large number of taxonomy terms, arranged in
 very deep hierarchies. Is this right? Can you give some numbers here -
 about how many folders do you have, and are they very very nested?

 I can see a change we could make that should improve performance here
 (switch from `in_array()` to `isset()`, and flip the array), but before
 making this change, I want to be sure that this isn't a symptom of a
 deeper problem.
