+// are not supported equally well by all compilers we'll use a
+// general trick that works well but just isn't as obvious to the
+// casual reader of the code. This way, for now, everyone executes
+// the smae code path. When C++11 support is more ubiquitous calls
+// to this function can be replaced by calls to the shrink_to_fit
+// method associated with the object.
