__bobo_traverse__ and convert them to NotFound. In debug mode
        a more verbose error message is issued, the same way it's done
        on attribute/item traversal.

      - Don't escape properties stored as XML (ie: having a
        __xml_attrs__ metadata set by PROPPATCH) when building a
        PROPFIND response.

      - If a PROPPATCH element value contains only a CDATA section,
        store the CDATA contents only.

      - Always unescape element contents on webdav.xmltools

      - Use saxutils to escape/unescape values for/from
        PROPFIND/PROPPATCH.

      - Make OFS.PropertySheet use the escaping function from
        webdav.xmltools.

      - Escape/unescape " and '

      - Set a default value of '' for the new 'alt' property as not to
        break existing content.

      - Collector #1443: Applied patch by Simon Eisenmann that reimplements 
        the XML parser used in WebDAV fixing a memory leak.

        is no longer taken from the 'title' property but from the new 'alt' property. 
        The border="0" attribute is no longer part of the HTML output except specified
        otherwise.

Forward port form 2.7 branch.

medusa's class monitor_server derives from asyncore.dispatcher, but
never called the latter's constructor.  As a result, the ._map attribute
set by 2.4's asyncore.dispatcher.__init__() never gets set, and calling
asyncore methods later dies with an AttributeError on ._map.  The fix
is a 1-liner, adding a call to the base-class constructor.

  2.3.4 or later.

Collector #1350: segfaults under SessionRig stress tester.  Since we perform a unfortunate monkey-patch in here to ZODB's Connection class, and in doing so we override the "close" method of that class, we need to do all of the things that ZODB 3.3's "close" method does, which includes unregistering a synchronizer.

The Python fatal errors occur only in a debug build now.

In a release build, unghostify() raises a Python SystemError
exception if it detects insanity, and ghostify() ignores the
problem (as ZODB 3.2 did, although it looks like 3.2 ignored
the problem by mistake).  This isn't *good*, because the
system is insane.  But it can become insane only by breaking
absolute threading rules, and that "should never happen".
Unfortunately, hundreds of things can go wrong if it does
happen, and we can't detect most of them.

In ghostify() and unghostify(), trigger a fatal error if the
object is insane.  This prevents a segfault (or, worse, arbitrary
memory corruption) later.

The test suite isn't bothered by this, and neither is bringing
up a Zope and playing around with it.  The only known cause
appears to be threading problems related to Transience.py,
partly explained in issue #1350.  It should be impossible for
these fatal errors to trigger via thread-correct use of ZODB.

I don't expect to keep these fatal errors in the code; indeed,
I'm checking this in only in Zope's *copy* of ZODB.  The intent
is to help whoever can make time for 1350 know whether that
problem still exists, until that problem goes away.  Unfortunately,
it's not even possible to raise an exception from ghostify()
(it's a void routine that "can't fail"), so it takes an extreme
measure to catch the problem as soon as it's visible.
