Call the Channels blocking method with timeout instead.

Using session variables net_write_timeout and net_read_timeout as the timeout parameter.

@fornaix Hi hi， could you please describe the problem?
Because I meet this problem very frequently "The last packet successfully received from the server was 1,401,847 milliseconds ago. The last packet sent successfully to the server was 1,401,848 milliseconds ago.
"

Does it relate with this PR?

@yiguolei hi, sure. I found this problem after killing a running query. The query is aborted and there are no running instances in be. But the mysql thread that receives the query is stuck there forever.

I meet this problem very frequently

Is this problem also stuck in channel blocking write or read?

@fornaix actually I do not know. because I could not get the jstack.

I found this problem after killing a running query. The query is aborted and there are no running instances in be. But the mysql thread that receives the query is stuck there forever.

If the query is aborted, and the mysql thread maybe hang in getNext and there is a timeout here. I think I will throw timeout exception.

Could you please explain it more detail?

My wechat number is monkgrandpa . Could you please add me, we could talk about it at wechat?
