 *  Fix: When a network interceptor mutates a request, that change is now
    reflected in `Response.networkResponse()`.
 *  Fix: Badly-behaving caches now throw a checked exception instead of a
    `NullPointerException`.
 *  Fix: Better handling of uncaught exceptions in MockWebServer with HTTP/2.

<p>
it can happen that <code>g</code> prints <code>2</code> and then <code>0</code>.

This fact invalidates a few common idioms.

Double-checked locking is an attempt to avoid the overhead of synchronization.
For example, the <code>twoprint</code> program might be
incorrectly written as:
