<p>The maximum concurrent streams setting only controls the maximum number

when this setting is set to 100, this does not limit the number of
concurrent streams that can be created by the caller.</p>
<p>It is recommended that this value be no smaller than 100, so as to not
unnecessarily limit parallelism. However, any value is legal, including
0. If <code>max</code> is set to 0, then the remote will not be permitted to
initiate streams.</p>
<p>Note that streams in the reserved state, i.e., push promises that have
been reserved but the stream has not started, do not count against this
setting.</p>
<p>Also note that if the remote <em>does</em> exceed the value set here, it is not
a protocol level error. Instead, the <code>h2</code> library will immediately reset
the stream.</p>
