I considered this, but allocating yet another object didn't seem like a
good idea.

It is about sharing with String. Typical usage of a StringBuilder will
be to create it, do a few operations to build the string and then call
toString on it. It would be nice to reuse the char[] in the String
(because typically the StringBuilder will not be used anymore), but this
turns out to be a pretty hard problem.
