Hi. I couldn't catch cce in IRC for while, so here goes: flow._Deferred does not handle errors properly. I cannot find the place where flow._Deferred.errback is called, and it doesn't work anyway. I put a short program that demonstrates the behavior on http://dunce.mine.nu:8080/flow_simplefailure_test.py No matter what I do, I cannot get "got from getPage yield" to get printed or errback to get triggered.
