[Bro] Bro restart not saving logs properly

I noticed that when I a restart bro using the cluster command that the current manager logs are not saved.  What end up in the logs directive is data for only a few minutes as if bro reopened the logs before terminating.  

Could some verify that bro work properly under bsd.  
I am running bro under linux and suspect that this is only a problem under linux and not bsd.

Yes, there are two options:

- file-flush.bro flushes all logs regurlarly (default: every 10s).

- the built-in function set_buf() disables buffering for a
particular log file; see the bro_init() handler in remote.bro for an
example. If there's not much traffic on the line, disabling the
buffering for conn.log shouldn't be a problem.
