Thanks for this pointer, and for the additional analysis. While i understand this problem much better than i did two days ago, i'm not sure whether there is an alternate proposal here for how to handle the situation. Do you have a suggestion for some other fix? It's tempting to remove the "controlling terminal" from the test suite entirely (e.g. by running it under "setsid --wait"), but i'm reluctant to do so because that is not the context in which most instances of notmuch will themselves be run, and i don't really want the test suite to be so alienated. So i'm unsure what to do, but i do want to try to move on beyond all this "testing the test suite" and start getting more e-mail-related features into notmuch again :P --dkg
