[ZODB-Dev] persistence errors with python2.5 64 bit linux

[Shane Evans]

The tests did show up the problem.

It seems someone beat me to opening the bug report:  
https://bugs.launchpad.net/zodb/+bug/153316  I found a related problem 
and added it along with a patch.

Unfortunately there still seem to be problems in my application and it 
looks like it's a zodb issue (or some dependency).  Since it was only a 
quick evaluation on my part, it looks like I'll have to go with 
something else. I'll return to it later if I have time.

Thanks,

Shane
