> We just found and fixed a serious concurrency issue in Localizer.  The HashMap in Localizer is accessed concurrently and under a high enough load, sometimes the HashMap data structure gets corrupted, causing infinite loops on servers.  We need to ensure that other places don't have this problem too.  Any application scope shared data structure (shared resources maybe?) should be checked and made concurrent for 1.3 final, if possible.
