I don't think it's an oversight; I'm not at all surprised that it
works this way.  

I assume that a pack removes this data.  If it doesn't, then that's a
shocking oversight.  A lot of the ZODB implementation is guided by the
principle that aborts are rare, so it's okay if they're more expensive
than commits.  This is just expensive in terms of disk space.

Can you say something more about how the behavior is affecting you?  I
guess I could be convinced that this is more of a problem that it
seems.
