That would work, however I just dont think that fits neatly into the ZODB in
any way since all objects are appended.

Well it would be threadsafe since the object cannot be written too by
multiple threads as discussed earlier it will keep try 3 times and then
fail. To me the ideal answer is a simple FileSystem product that allows you
to mount a file system inside the ZODB. This would implrement locking and be
hence be thread safe. Its a real science project. This would also have to be
ZEO friendly, but to be honest for my use and most other peoples, this isnt
a huge concern.

Me too but its sloooow.
