After starting from command line bitocoind, it can require minutes to have bitocoind to be real responsive, for example:
`$ ./bitcoin-cli stop`
`error: {"code":-28,"message":"Activating best chain..."}`

In such situation, I had sometimes to "kill -9" bitcoind to stop it.
I would like to be able to stop bitcoind in clean way.

p.s.:
