Actually ZServer requires threads, it uses one thread for Zope and one for
the server... but this would be considered "single threaded" from a DA
perspective (see the document I'm going to send out this afternoon to the
list summarizing a lot of DA issues).

You just need to run ZServer with the '-t 1' or '-t1' option,, which says to
only use 1 thread max.
