I'd suggest 1) not writing a unit test framework, and instead using
trial, and 2) instead of using stackless, use greenlet + my
gthreadless module that integrates greenlets and Deferreds
(sandbox/radix/gthreadless.py).

Alternatively, if you don't want to use greenlet, as Bob said, just
use deferred generators
(twisted.internet.defer.{deferredGenerator,waitForDeferred}).

HTH, HAND :-)
