Our intranet server, which is two zope servers running on
top of ZEO frequently "hangs", meaning that a url request
tries forever to load data and never returns.

I don't know if it is related but I frequently see the following
three errors:

This appears on stdout every now and then:
[root@thepoint Zope2]# Unhandled exception in thread:
Traceback (innermost last):
  File "/mnt/disk1/Zope2/lib/python/ZEO/zrpc.py", line 149, in connect
    self.aq_parent.notifyConnected(s)
  File "/mnt/disk1/Zope2/lib/python/ZEO/ClientStorage.py", line 166, in notifyConnected
    self._info.update(self._call('get_info'))
  File "/mnt/disk1/Zope2/lib/python/ZEO/zrpc.py", line 190, in __call__
    return loads(r[1:])
SystemError: Failed to import class append from module __main__

These next two show up in my stupid log fairly often:
