>Subject: [PATCH] s3:winbind: Only ever handle one event after a select call
>
>While handling an fd event, the situation with other fds can change. I've just
>seen a winbind stuck in the accept() call on the privileged pipe. I can only
>imagine this happen because under high load we first handled other requests and
>meanwhile the client on the privileged pipe went away.
