Hm, shouldn't it be possible to bind a pipe(2) to stderr instead? I
mean in the process of running the notmuch binary (i.e. somewhere
along the lines of fork and exec)?

I've implemented this for alot, which does not use the binary but
directly calls into libnotmuch, but does so in a helper process. Said
helper has a pipe(2) on stderr and the alot process reads from it and
turns any line into a log message.
