于是直接在命令行下，mkdir test
结果提示：
mkdir: cannot create directory `test`: Too many links
我看了一下，那个目录下有狂多的目录，猜想是不是Linux也有目录限制。记得Windows是有的，以前就碰到过。
搜索了一下，原来是有32000的限制。

I already talked to Drew, there is a limit of 32,000 links in an inode,
which in turn limits the number of directories in a single place to 31,998
There is no way to increase this in ext2 without changing the inode format,
which will not happen before a little while (dixit the major ext2 FS guys at
ALS)
Solutions:
1) use base/d/di/directoryname name splits
2) use another filesystem (note that the default filesystem on freebsd, and
probably many other FS do also have a limit of 32K directories or
somesuch, so for portability, you want solution #1)

原程序是每查询一个，就生成一个目录，怪不得有这么多目录。于是建议他以dir/dir或dir/dir/dir的形式存储，问题解决：）
另外，同一个目录下的文件不要太多，听说超过1000个文件或目录时读取速度就有些影响了。
