Currently, when we open a new channel, we pass it an InboundChannelBuffer. The channel buffer is preallocated a single 16kb page. However, there is no guarantee that this channel will be read from anytime soon. Instead, this commit does not preallocate that page. That page will be allocated when we receive a read event.
