Comment (by dbaston):

 Replying to [comment:3 pramsey]:
 > Fixing homogenize to return a full copy seems preferable to deep cloning
 the return from homogenize, ISTM.

 Agreed.  I don't think we actually need a clone though, I think it's
 sufficient to just avoid freeing our input GSERIALIZED before we've
 serialized our output.  If there are no concerns with the attached patch
 that does this, I'll commit it.
