[ZODB-Dev] Objects ghostified during a transaction

[Florent Guillaume]

I'm confronted to a bug in CMF (http://zope.org/Collectors/CMF/198) 
where a _v_ variable disappears in the middle of a request (and reverts 
to its class-default of None).

I want to fix this by removing the reliance on _v_ variable, but to 
write a unit test for it I'd like to be sure of why it happens. Can an 
object be deactivated *in the middle* of a transaction? As a datapoint, 
it's quite likely that some partial transactions 
(get_transaction().commit(1)) occur when the bug appears.
