> this issue is introduced in providing netty server for bookie.
> in BOOKKEEPER-294, we agreed on the start sequence of bookie:
> 1) bind bookie port first (to avoid two processes running at the same host).
> 2) start bookie (e.g initialize bookie storage and replaying journals)
> 3) start nio server to accept incoming requests.
> but after refactoring for netty server, step 1) is combined to be executed in
> step 3), so two processes could have chance to run at the same time replaying
> journals. this is pretty bad.
> we need to change the code to stick on the sequence described above.
