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
