把max_statements设置为0。
c3p0在同时关闭statement和connection的时候，或者关闭他们之间的时间很短的时候，有时候connection并没有被关闭，因为有些preparedstatement还在被cached住。这是c3p0的作者自己说的。

1，简单替换表达式
替换命令可以在全文中用一个单词替换另一个单词：
:%s/four/4/g
“%” 范围前缀表示在所有行中执行替换。最后的 “g” 标记表示替换行中的所有匹配点。如果仅仅对当前行进行操作，那么只要去掉%即可
如果你有一个象 “thirtyfour” 这样的单词，上面的命令会出错。这种情况下，这个单词会被替换成”thirty4″。要解决这个问题，用 “\<” 来指定匹配单词开头：
:%s/\<four></four>
显然，这样在处理 “fourty” 的时候还是会出错。用 “\>” 来解决这个问题：
:%s ...

用一个空的 fake 包来包涵OOo
