I did understand this *BUT* you do not have a choice.
While a single ExternalMethod runs as "root", the complete
Zope process runs as root -- and this applies to all
requests which are run in parallel with your ExternalMethod.
Please reread my former message.
If you have touble to understand the terms "thread" and/or "process",
consult Wikipedia to get some insight.
