As a starter, maybe sem_open() would be easier, because it seems like it could map very well to a /servers/sem/ directory where named semaphores would live.

sem_open was done in 749cd2ca7893702f762de9d9852a39973eb044a0
mutex_init was done with the mutex rewrite to gsync

We are still missing it for barriers, rwlocks, conds.

E.g databases like postgresql like using process-shared semaphores and mutexes.  The Hurd should support them.
