We do use IPC shared memory but it is a single large one, shared by multiple
levels. We are currently looking into using a similar solution based on
When a new level is created, a file representing that level could be
a common path which could be locked by the init process of that level.
Parent levels could query the locking pid of that file to get the pid
of the init process of the required level. Then it could open a file
and use the translate_pid API for further translations.
