XAPIAN_FLUSH_THRESHOLD is a C string in the environment, so users may be tempted to assign an empty string in in their shell, e.g. `XAPIAN_FLUSH_THRESHOLD= <command>' instead of using `unset' POSIX shell built-in. With either a value of "0" or "" (empty string), Xapian will fall back to its default (10000 documents), which causes grief for memory-starved users.
