 <code>IOException</code> may be thrown. This is primarily useful in a
 finally block, where a thrown exception needs to be logged but not
 propagated (otherwise the original exception will be lost).

 <p>If <code>swallowIOException</code> is true then we never throw
 <code>IOException</code> but merely log it.

 <p>Example:

 SomeStream stream = new SomeStream("foo");
 boolean threw = true;
 try {
   // Some code which does something with the Stream. May throw a
   // Throwable.
   threw = false; // No throwable thrown.
 } finally {
   // Close the stream.
   // If an exception occurs, only rethrow it if (threw==false).
   Closeables.close(stream, threw);
