  71 In the error-handling paths of notmuch_database_open, we call\r
  72 notmuch_database_close, which "delete"s several objects referenced by\r
  73 the notmuch_database_t object.  However, some of these pointers may be\r
  74 uninitialized, resulting in undefined behavior.  Hence, allocate the\r
  75 notmuch_database_t with talloc_zero to make sure these pointers are\r
  76 NULL so that "delete"ing them is harmless.\r
