Hi all, I read in several mails that 'reportlab is not thread safe' in combination with zope. I'm running zope 2.3.3 with python 2.1.3 and reportlab 1.14 on linux 2.4.16 Can anybody tell me as simple as possible what 'no thread safe' in practice means ? As far as I know every authenticated user in zope has his own thread. Will this be a problem ? Regards, Dirk
