     95 *         - may not use any other synchronization primitive,
     96 *           save for another `fibril_rmutex_t`. This includes nonblocking
     97 *           operations like cvar signal and mutex unlock, unless otherwise
     98 *           specified.
     99 *         - may not read IPC messages
     100 *         - may not start a new thread/fibril
     101 *           (creating fibril without starting is fine)
     102 *
     103 * Additionally, locking with a timeout is not possible on this mutex,
     104 * and there is no associated condition variable type.
     105 * This is a design constraint, not a lack of implementation effort.
