What you *really* want to do is apply the patch I posted earlier that 
makes render handle deferreds properly, and then do:

from twisted.web import server, resource, static, script
from twisted.internet import reactor
from twisted.internet import threads

def doLongPageGeneration():
      return "<html><b>H</b>ello, <b>W</b>orld!</html>"

class Simple(resource.Resource):
      isLeaf = True
      def render(self, request):
          return threads.deferToThread(doLongPageGeneration)

site = server.Site(Simple())
reactor.listenTCP(8080, site)
