Channels are cheap, but unless they get garbage collected (and I assume not closing them will prevent this), they will still take up some resources.
Related and important is that you shut down any go blocks that you create in IWillMount, especially if they take from a channel which may still be receiving data (eg: through mux or pub/sub). If you don't shut these down, they will continue to run even after the component has unmounted and if the component is later mounted again, you will have multiple go blocks doing the same thing! Besides using resources, this can actually be dangerous if you are accessing owner inside the go block (eg to set local state) as you may end up accessing an unmounted owner. The simplest solution is having a kill channel that you listen on using async/alt that gets closed in the IWillUnmount and that terminates the go block.
