String insertion sort
Let's add the coding declaration, it's good practice in Python 2
Limited GNU parallel to using 1 core

It's not really "parallel" anymore, but timing parallel jobs when they share

My quicksort implementation
Fixed some bugs with radix sort
Let's see if insertion sort speeds things up any
Let's make the output format a bit more user-friendly
Preliminary tests suggest that insertion sort indeed speeds these up somewhat, so let's use that
This should make sorting in spreadsheet editors easier
Fallback to insertion sort is default, now
Let's not throw Arturs's work down the trash
Looks like that's exactly what I did by deleting quicksort.py in the branch

Whatever, I just copied it back from GitHub.  I've got an idea on where
Arturs's code fails anyway
Fixed timesink
