Jason,
Robert is right...
The point is ARC is the caching module of ZFS and majority of the memory
is consumed through ARC.
Hence by limiting the c_max of ARC we are limiting the amount ARC consumes.
However, other modules of ZFS would consume more but that may not be as
significant as ARC.
Expert, please correct me if I am wrong here.
Thanks and regards,
Sanjeev.

That's the idea however it's not working that way now - under some
circumstances ZFS could still consume much more memory - see other
posts lately here.
