This code actually results in a subtle race condition as channels need to be locked internally. It also won't work for other implementations of channel, of which there are several in core.async besides ManytoManyChannel. (For example, map< returns a reified channel.) Knowing whether a channel

Two notes: 1)The provided core.async go-loop macro is a small enhancement for the (go (loop )) case. 2) Be careful using when using falsey tests like when or if - these will stop on nil but will also stop on false coming through the channel. Might be ok here, but it's something to be aware of.
