I think Titus was talking about the ominous warning in the Durus docs
about "cannot be used from multiple threads in a single process".  Which
brings up a related question I've been pondering.  How do you migrate
data between Durus and ZODB?  I may want to use Durus but I'm concerned
about that thread limitation.  Not that it matters now but it may in the
future.  I notice Durus classes are persistent through a persistent
mixin, while ZODB classes are persistent through a different mixin.  If
I do need to port a Durus database to ZODB, do I have to create a
parallel tree of objects and copy the attributes from each object to the
other, or is there an easier way?
