I've got #1 and #3 working.
Number 2 is going to be a bit more work because the formatting of
arguments appears to be scattered around in hundreds of different
functions [as opposed to the Python code where there is a single
function that formats/prints the arguments for all syscalls].
If anybody is interested, I can post code...
