The pre-write code encounters a situation where usleep will die under multiple threads.Look at the log is the thread stuck, so gdb went in to see, but did not find the deadlock, or normal stay in the usleep, and finally found that it is usleep in

1:sleep ()The minimum unit of seconds.When using Sleep/ulseep/select, because the thread will go to sleep state, and then wake up, if the single execution problem is not small, if the number of cycles executed more, then the difference is very large.

Thread congestion caused by usleep:   The thread is inexplicably congested. When we use GDB attach, we find that the thread is blocked in the usleep call. It seems that we have heard of such problems from other colleagues. Change usleep to
