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 --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQTJDm02IAobkioVCed2GBllKa5f+AUCXOQeNQAKCRB2GBllKa5f +L0eAQCH7xuyAi9TptS+mogAw4kx5p/XV5GQlVLDHlS8tfg3vgD/SWdgxZR/D3ZL ZMT3gERYHm9+LL01dc6+nRUJ61T5IAw= =1k4T -----END PGP SIGNATURE----- --=-=-=--
