Looking at the output of trace when trying to assemble the "Hello, world!" .s file, the issue is the same: Passing a size of -32 to write(2). I do notice that there's a difference in df output on the Sun with my hack in place on the NFS server, but still plenty of negatives:

                    -1619144  733976-1223584    80%    /home

So there's more to tweak. At least my next build will be super-quick!
