- * NOTE: the pointer-tracking support in NSS/base currently relies
- * upon NSPR's CallOnce support.  That, however, relies upon NSPR's
- * locking, which is tied into the runtime.  We need a pointer-tracker
- * implementation that uses the locks supplied through C_Initialize.
- * That support, however, can be filled in later.  So for now, I'll
- * just do this routines as no-ops.
