 This approach is similar to wait morphing for locks~\cite[p.~82]{Butenhof97} and improves performance in a few ways.
 First, each thread interacting with the channel only acquires and releases the internal channel lock once.
-As a result, contention on the internal lock is decreased, as only entering threads compete for the lock as unblocking threads do not reacquire the lock.
+As a result, contention on the internal lock is decreased; only entering threads compete for the lock since unblocking threads do not reacquire the lock.
 The other advantage of Go's wait-morphing approach is that it eliminates the bottleneck of waiting for signalled threads to run.
 Note, the property of acquiring/releasing the lock only once can also be achieved with a different form of cooperation, called \Newterm{baton passing}.
