Ok, and I see that beforeCompletion(t) has to check t.status to find out 
when it is called (if the transaction is ACTIVE it's ok, otherwise it's 
been called by abort() -- the fact that abort() calls it should probably 
be documented).

But as Julien said we'll have to find another way using ZODB 3.2...
