   * called frequently, it will be a few orders of magnitude faster than
   * |WalkTheStack|. However, the cache uses a lot of memory, which can cause
   * OOM crashes. Therefore, this should only be used for things like refcount
   * logging which walk the stack extremely frequently.

   * Tell nsTraceRefcnt whether refcounting, allocation, and destruction
   * activity is legal.  This is used to trigger assertions for any such
