---------------------------------------

I recommend using this:

> Make AdoNetAppender not to stuck application process

> The original AdoNetAppender could stuck application during log insertion.
> Because it use the sync method call to do database insert, once the DB is 
> unavailable or table was locked.
> I change the implementation that has an inner queue inside to store the 
> messages, and the other independent thread will be going to cunsuming the 
> queue messages and do DB insertion.
> This implementation will not have any impact on application performance and 
> much stable.
> Trade off: Once the queue max buffer was full, the later coming log message 
> would be ignored and gone forever. But log4net is not designed for guarantee 
> delivery in purpose, right? So it's not big deal at all. :)
