Subject: Internal Iterative Deepening (in Crafty)

I have been looking through the source code for Crafty and noticed that the
Search routine used "Internal Iterative Deepening" to get a good move to play at
an internal node.  I was puzzled as to the actual benefit of this routine.  I
can see that it will return a good move but assume that this is a costly method
for finding a such a move.  Does it really speed up the search by that much?
How much?  Does "everyone" do it?
