[IMPROVEMENT] Implement multithreading

[thealphadollar]

Most of the process that takes time in the client are network I/O which can be
made a lot fast using multi-threading.

Using POOL from multithreading library it can be implemented, and the place of
implementation can be the passing of the list of channels.

This would make the process a lot faster, and save a lot of time.

This sounds like a good idea! 😃

Recently, I came across a good article/rant on multiprocressing.Pool in Python. I suggest reading it after you have a basic idea of how the package works and its capabilties. Apart from this, I think you will also have synchronise the results you get back from the network calls.
