[Zope] Is there a way to look at the "raw" data making up an object in the ZODB?

Thanks, Andy.  That's pretty neat.  It's never been easier!!

Now getting to the meat of the problem I have:  I've located the
name of the attribute that is too large.  The problem is that I've
been unable to get rid of the attribute completely.  I've used a "del" 
in my __setstate__, I've restarted Zope completely, and I've packed
the database.

When I use the debugger as above, the attribute that I got rid of
is no longer there, but when I export the object from the ZMI, the
.zexp is 500 KB, and I can see the name of the attribute in the
.zexp.   Why is this attribute still hanging around?

Thanks in advance,
