Comment:

 Hi Jeremy, I create one branch trac519, would you like to have a test
 again?

 Again, I did some change to stats and boss module.

 Old logic:
 When stats module starts, it will send the command "sendstats"  to boss,
 then wait for the answer in non-block mode, when boss receive command
 "sendstats", boss will send command 'set' to stats, then wait for the
 answer in non-block mode.

 The problem is: wait for answer in non-block mode will generate orphan
 answers(never be read again). but if change it to in block mode, it will
 'deadlock', since boss and stats wait for answer from each other.

 New logic:
 when stats module starts, it will send a new command "getstats" to boss,
 then boss will send back the stats data in the answer.
