One thing about this test is that it does produce a lot of output (when we update the contracts impl. I think we'll split it up a bit). One of the expect fixes is to increase its internal buffer (to 8k from 2k IIRC) I don't see this test "twinkling" in my runs, which might indicate that either the expect fixes - or the version of TCL I'm using resolves it. Here https://github.com/iains/build-scripts are he scripts I use to setup my build and test environment (some of the Xcode tools are too old for development, and obviously one has to provide dejagnu at least).
