输入：道路千万条安全第一条
输出：千万条安全第一条
改变字符串，结果相同；小于8个字的字符串没有问题。
总感觉是哪里的buffer满了导致的

好像必须输入得足够慢才行，已在 1b04eb1 中增大了默认按键延时设定。

推测的原因：Windows默认的按键缓存队列长100，而每个字需要按键6次，每次按下和松开两个事件共12次事件，所以8个字之后队列满了，导致前面的被顶掉。

（缓存队列大小设定在注册表里：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kbdclass\Parameters\KeyboardDataQueueSize，供参考）
