- Fixed vulnerabilities in the ZEO network protocol that allow:

CVE-2009-0668 Arbitrary Python code execution in ZODB ZEO storage servers
  CVE-2009-0669 Authentication bypass in ZODB ZEO storage servers

- Limit the number of object ids that can be allocated at once to
  avoid running out of memory.

- The "lawn" layout was being selected by default if the root of
  the blob directory happened to contain a hidden file or directory
