Comment 10 for bug 1040735

The lock contention seems to be mainly about buf_pool mutex in buf_LRU_try_free_flushed_blocks and buf_flush_start. However, I have not been able to reproduce it with configuration in description and sysbench. (also in master slave mode). In the backtrace provided there isn't much in buf0buf except for innodb monitor print.

 If steps to reproduce this can be provided(along with cnf) , that would be great.
