As of a few seconds ago we're using ArrayList instead!  It shows
significant memory savings.  See the check-in message at
for details.

Simple timings also show build time improvements with the change to
ArrayList.  For the largest file (xlink.xml) build times varied between
4000-4400ms with LinkedList and are now 2800-3500ms with ArrayList.
