The old ZODB object cache had a notion of cache age. Objects that
hadn't been accessed within a certain time were removed from the cache.
This feature was removed in Zope 2.6, but all of the APIs that
controlled the age (sometimes called cacheDeactivateAfter) were kept
around.

transaction management is integrated into the Zope application.

The nice thing about fixing this bug is that the code continues to be
improved. The last round of beautification made the code

We have made a beta release of ZODB 3.1.1 and ZEO 2.0.1. The primary
change is a fix that allows transactions with multiple databases to
run without deadlock.
These release will correspond exactly to Zope 2.6.1b1, which will also
be released today.

callable() returns True for any instance. Since PersistentList is an

We recently discovered that ZODB3 applications, like Zope 2.6, can
deadlock when run in a system that uses multiple storages. This was a
fundamental design flaw in ZODB that, happily, has a simple fix.

The documentation for ZEO contains the following note about product

but I don't understand the problem exactly or whether it has been

I am happy to announce that ZEO 1.0 final was released today.
Zope Enterprise Objects (ZEO) provides the ability for multiple
processes to use a single Zope Object Database. ZEO turns the Zope
object system in a distributed architecture, allowing multiple
processors, machines, and networks to
I have just released ZEO 1.0 beta 6. It's been almost six months
since the last beta release, so it was surely time. This release
fixes two bugs that Zope Corp. has recently run into in the field.
See http://www.zope.org/Products/ZEO/.

Python 2.1.2 has some extra safety checks that will immediately detect
the stack overflow bugs that caused problems with PythonScripts before
2.4.4. The fact that you're seeing crashes in the garbage collector
and not assertion failures in Python/ceval.c makes me think the
