+The function `notmuch-test-wait` called `get-buffer-process` and\r
+`sleep-for` in a loop. On some emacses neither of these cause emacs\r
+to check whether the process has exited and update it's status\r
+accordingly. In this case the loop does not exit.\r
+\r
+The function `sit-for` goes into event loop via `read-event` function\r
+call. `read-event` does not return when process exits but the event\r
+loop used to determine whether there is keyboard, mouse, etc. event\r
+updates the process status as a side effect of the (more generic)\r
+event loop. `sit-for` is used here to restore the event into queue\r
+in the improbable case `read-event` consumes an event.\r
