BTW, this is due to version skew in asyncore....

A nice way to avoid having to remember this is to import
ZServer in your custom_zodb module.

If it's an EM,you can go to the edit page and select change.
The EM is always reloaded when it's changed.

Again, I can live with it implementing __getattr__, especially
if it uses it *after* normal attribute lookup.

There's no need to mess with set/delattr.

In general, I think really big folders should use getitem, since
they really wanted to be treated as collections rather than instances
(wrt subobjects).  I think getattr makes sense in this case
for hysterical  reasons.
