+   * There seems to be a deadlock in GObject type registration from
+   * different threads based on some different parts of the type system.
+   * This is problematic because we occasionally race during startup in
+   * GZlibDecopmressor's get_type() registration.
+   *
+   * Instead, we'll just deal with this early by registering the type
+   * as soon as possible.
