I've been slow to respond, mostly busy, partly checking some freebsd
facts...

The patch is mostly good, but there are a few issues i am going to
mention a bit later -- now I just have few minutes...

IIRC you're a freebsd port maintainer and would like to have more
certainty that every new test patch doesn't break your test.
In general we desire more portability overall e.g. things work on
linux, *bsd, macos, solaris...

But, for now I'd like you to test the following script which
I named `make-test-freesd.sh` (well, that could also work on many other
OSses) and tell why it would not work ;) ... in that there is one hint
how the patch should be improved :D

run it instead of `gmake test` in notmuch source directory.
