*wistles*.  Cool hax bro :D.

Unfortunately, this will be (completely?) untestable (yes, I know we don't have
tests yet, but they're definitely planned).

I'll cook up a CL which will be a more scalable/testable way to support dynamic
step reconfiguration :)

I was expecting more of a "omg, this is terrible" reaction, so thanks! :)
 
sweet! looking forward to it. Could you CC me on the review?

Ick. I think I'd (much) rather force ALL stdout for annotator steps to be
non-interactive.

[mkosiba (inactive), 2013/05/10 15:08:52]

ah.. exciting news here - this was caused by the run_recipe tool passing
--keep-stdio to annotated_run.py. After removing that option it works fine
without the cat too!

[iannucci, 2013/05/10 20:21:53]

Ah, sweet! I should have remembered that.

It would be nice if there was a clever way to disable the tty-ness of the stdio
fd's without closing them completely. In particular, pdb should still be
functional (that's why I added keep-stdio in the first place)... I'm not really
thinking of a way though.

How hard would it be to add a non-interactive arg to repo?
