I correct my previous statement.  Yes, this is true.  Pickles generated 
with 1.0.1 cannot be read by version 1.0

However, pickles generated with 1.0 can be read by 1.0.1.   It is 
typically not the case that pickles created with newer versions of the 
code will work with older versions.   I obviously didn't think that was 
something to be concerned about because it slipped my mind.

Changeset 3411 is the reason where the hasobject member of the data-type 
object was given more bits (and therefore needed to be saved).

Sorry for the trouble,
