I have a feeling that you're doing something strange, like using the
CGI module from inside the same process? Twisted Web runs CGIs just
like any other webserver does -- in a seperate process.

There are a couple of classic tricks, which vary between deferred when
there's something specific you're waiting for or reactor.callLater loops
if you just want to break apart something big and reactor.callInThread
when it is too hard to break it apart.

It was probably better to request.finish() yourself, and

The correct way is to write a -y'able file.
# call this pybloxom.ypy
from twisted.internet import app
from twisted.web import server
root = CreatePyBloxomResource()
site = server.Site(root)
application = app.Application("pybloxsom", uid=33, gid=33)
twistd -y pybloxom.ypy
