Benedict Elliott Smith commented on CASSANDRA-15308:
----------------------------------------------------
bq. There is no API from OutboundConnection to release all remaining capacity
There isn't, but we _can_ know how much we should release, and simply invoke
{{unsafeReleaseCapacity}} with the amount, no?
This test could also do with some better comments, such as explaining that we
"reserve capacity" before we begin releasing to ensure we cannot release more
than we have acquired. This is particularly important given the misleading
comment at the bottom indicating the ability to release more than we acquire
(since it only really means more than we acquired concurrently, else we would
be at risk of assertion failures)
