Hi everyone!

Anyone know an efficient way to randomize an array (I have a
sorted array that I want unsorted). Initially, I tried something like
this:

array = findgen(1000000)
unsort = array[sort(randomu(seed,1000000))]

It works, but sorting on a million elements is rather slow. Anyone
know a faster way?
