+Hm, shouldn't it be possible to bind a pipe(2) to stderr instead? I\r
+mean in the process of running the notmuch binary (i.e. somewhere\r
+along the lines of fork and exec)?\r
+\r
+I've implemented this for alot, which does not use the binary but\r
+directly calls into libnotmuch, but does so in a helper process. Said\r
+helper has a pipe(2) on stderr and the alot process reads from it and\r
+turns any line into a log message.\r
