Do Hurd's RPCs have to be used in order to provide process-shared semaphores?
I thought we could use shared memory between network drivers and pfinet in 
order to improve their performance. If Hurd's RPCs have to be used when we 
synchronize relevant operations, we might not get any benefit by using shared 
memory.
When process-shared semaphores and mutexes themselves are in the shared memory, 
can we not use the similar implementation as the ones in the same process?
