[ZODB-Dev] ZODB load/save tracing

[Adam Groszer]

Hello Christian,

Gosh, that looks simple. A simple decorator pattern on the storage.

So I shall create a branch, something like
svn://svn.zope.org/repos/main/ZODB/branches/tracing-storage
from
svn://svn.zope.org/repos/main/ZODB/trunk
and start there?
