Just now the maillist notified the mail was not sent successfully. Thus

Do you make tests with your commit in the local hosts?


I have applied your commit and made tests in my local host. I run the 
tests for 10000 times.

Sometimes problems occurred. I am not sure if this problem is related 
with this commit or not.

I will make further investigations about this problem.
