sharing data between processes
Yes, this is the most efficient way if both processes run on the
same machine.
With a standard file you have sharing and locking problems.
And shared memory may not be backed by a file - you could
use the swap file instead, provided you have a mechanism for
exchanging the appropriate handles across the two processes.
