i think method addForeignJavascript should looks like:
public static void addForeignJavascript(String in)
{
if (!getInstance().foreignJavascripts.contains(in))
{
getInstance().foreignJavascripts.add(in);
}
}

it prevent render on echo "start" page multiple <script src=... statement
if browser page was refreshed (eg. by F5 key)

ps. sorry for my english.
