Sorry, I just stumbled across HADOOP-6109 which made this change in
trunk, I was looking at the Text in 1.0.2. Cant get this fix get
backported to the Hadoop 1 versions?

Why does Text.setCapacity only expand the array to the length of the new
data? Why not instead set the length to double the new requested length
or 3/2 times the existing length as in ArrayList so that the array size
will grow exponentially as in most dynamic array implentations?
