oops, sorry.. given example is wrong.

it is just:

json := db streaming  documentAt: '12345'.

or:

json := db documentAt: '12345'.

the difference between these two, that first will start parsing data
once it available,
while second will wait till all document data will be retrieved.

Currently, there are some subtle bugs in JSON parsing code, like using
#peek: which prevents it from working
with SocketStream. Either SocketStream needs fixing, or JSON parser,
to avoid using it.
