interface nsIRunnable;

 * This service allows access to the current thread's Chromium MessageLoop
 * instance, with some extra sugar added.  If you're calling from C++, it may
 * or may not make sense for you to use this interface.  If you're calling from
 * JS, you don't have a choice!
 * Right now, you can only call PostIdleTask(), and the wrath of khuey is
 * stopping you from adding other methods.
 * nsIMessageLoop's contractid is "@mozilla.org/message-loop;1".

interface nsIMessageLoop : nsISupports
   * Posts a task to be run when this thread's message loop is idle, or after
   * ensureRunsAfterMS milliseconds have elapsed.  (That is, the task is
   * guaranteed to run /eventually/.)
   * Note that if the event loop is busy, we will hold a reference to the task
   * until ensureRunsAfterMS milliseconds have elapsed.  Be careful when
   * specifying long timeouts and tasks which hold references to windows or
   * other large objects, because you can leak memory in a difficult-to-detect
   * way!
