Great hint.  I had just assumed DateArrays and TimeSeries couldn't be  
pickled because Dates can't be pickled.  This makes it all much  
easier.  I've been str() single Date instances, which has been working  
fine.  single-element DateArray is probably easier.

First I have to learn some basic Python multiprocessing stuff.
