/**
 * Permission to use internal thread pools (see GetThreadPoolAction).
 *
 * A ThreadPoolPermission contains a name (also referred to as a
 * "target name") but no action list; you either have the named
 * permission or you don't.
 *
 * ThreadPoolPermission defines two target names,
 * "getSystemThreadPool" and "getUserThreadPool", for permission to
 * get the system thread group pool and permission to get the
 * non-system thread group pool.
 *
 * A ThreadPoolPermission implies the following:
 *
 * - permission to access the thread group designated by the target
 *   name; see SecurityManager.checkAccess(ThreadGroup)
 *
 * - permission to execute a NewThreadAction, which requires
 *   RuntimePermission("getClassLoader") and
 *   RuntimePermission("setContextClassLoader"); more practically,
 *   this is permission to have a Runnable executed with the system
 *   class loader as the context class loader
 *
 * - permission to execute a Runnable without the caller's
 *   protection domain in force
