When two or more clients try to connect to the same IRC network simultaneously, for the first client hitting the server, we create a bot instance to connect to the IRC server, and for the subsequent clients, we try to reuse the existing bot and start sending messages to the IRC server. But there's a time, when the IRC bot is instantiated, but not yet connected to the IRC, and the other clients try to send message to the IRC server, and it fails.

Solution
We need to use some kind of mutex to block other client requests until the IRC bot is connected to the IRC server.
