What is not thread safe about SimpleDateFormatter?  If this is true that 
seems kind of serious!  (I will take a look at the source tonight but it 
might help if you gave me a hint)

Anyways, this thread safety business sounds like something that might be 
useful to a lot of programmers out there.  I will take a look at what 
you've done in joda and see if I can't figure it out.  Maybe we could 
make a thread-safe version of SimpleDate Formatter be part of the 
proposed TimeUtils/DateUtils/whatever in commons-lang?
