I actually have a partial decoding function written which is
supposed to be used for a strace rewrite. It was supposed to
be used for all syscalls and datastructures but it should work
just fine for this as well. I might have time to get that working
next week, but I can't make any promised (I'll be in tokyo
for a OSDN-JA event).

That should really be done through a configuration file or
a commandline option.
