Sadly, even bubble sort would be better than the selection sort being used
here. It's guaranteed to be O(n^2) in all cases.
I just got through replacing that entire function in my repo with a call to
qsort() from the standard library last night myself. Faster (although
probably not material to most deployments) and less code.
