I wasn't sure what I should call the bug or even what severity to give it so 
for now I have put the patch at.

https://github.com/Immudzen/MonkeyOFSImageFile/blob/master/blobpatch

It is a diff to zope 2.13 checkout from svn and the diff was generated 
according to the link provided.

This monkey patch is probably not suitable to be directly merged into zope 
though because I removed a lot of the pdata support. It can still serve pdata 
structures just not write them anymore since that did not seem important 
anymore but would need to be for a real patch to zope itself.

For my own usage I just needed to convert everything to blobs since that 
provided some very nice gains. If this is useful to others though I am willing 
to put in the work to make it a real patch to zope that would preserve the 
pdata stuff if needed.
