[Zope] UnpickleableError: Cannot pickle <type 'thread.lock'> objects

[Dylan Jay]

I'm having some ZODB troubles.
I'm getting the following error. The problem is I'm not using locks in the 
objects that are being changed. I do have a lock being used with the 
Schedule object which is in the acquisition path. but this lock was a module 
variable rather than a attribute so that shouldn't matter should it?
I've also taken the lock code out altogeather now and I'm still getting the 
same error. Any ideas?
