Could you not store the state of the thread in some state storage object (on SystemExit) and pickle that? Then when Zope restarts, have an __init__.py in a Zope product look for that pickle (in a file or ZODB) load it and restart the threaded task where it left off? /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association [EMAIL PROTECTED] \---------------------------------------------------/ _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
