+ NOTE: the boolean parameter in the cache constructor lets you
control whether the cache should enforce a strict memory limit by failing the
read or iteration in the rare cases where it might go larger than its capacity.
Due to a

option cannot be used

set this to true, you should NOT pass the cache in to the
<code>WriteBufferManager</code> and just control the write buffer and cache
memory separately.</sup>
Review comment:
It looks like this (and some other stuff in the config-streams file) has
come along for the ride. We should make sure it's referencing behavior that was
released, not behavior that will be released next. Can you double-check that
this actually is in reference to 2.6.0, and not 2.6.1+?
