Well, except for "ioctl()"s (and except for "mmap()" of devices - S5R4's
version of the RFS protocol will, I think, support "mmap()" of files
over the network, but there's a bit of work involved in letting machine
A map machine B's frame buffer into its address space :-)).  S5R3
definitely doesn't canonicalize "ioctl()" arguments; S5R4 has a
mechanism for doing so on STREAMS devices - this could, I think, be done
for non-STREAMS devices as well, but I don't think it was.
