One solution is to change names just before we pickle, then change
back after unpickling.
saveData = Data
Data = saveData.__class__
should restore sanity, and allow:
pickle.dump(saveData, file)
It is a pretty crude hack, however, and as Gary says, raises lots of
questions as to what will happen if a state is loaded on top of the
existing, etc...
I've tried the suggestion but the unit test gives:
======================================================================
ERROR: The pickling and saving of the relax data storage singleton.

Traceback (most recent call last):

Can you show me the context of this error - UnboundLocal looks to me
like an implimentation issue rather than a fundamental problem with
the approach.
Removing the line 'Data = saveData.__class__' gives:
======================================================================

Yes, I guessed that bit would be important!
