/**
 * {@link Callable} that nominates another claassloader for serialization.
 *
 * 
 * For various reasons, one {@link Callable} object (and all the objects reachable from it) is
 * serialized by one classloader.
 * By default, the classloader that loaded {@link Callable} object itself is used,
 * but when {@link Callable} object refers to other objects that are loaded by other classloaders,
 * this will fail to deserialize on the remote end.
 *
 * 
 * In such a case, implement this interface, instead of plain {@link Callable} and
 * return a classloader that can see all the classes.
 *
 * In case of Hudson, {@code PluginManager.uberClassLoader} is a good candidate.
