Cool!

Well, first of all, get a Hurd system, get aquainted with it (play
with settrans & co), drop by #hurd on freenode and say hi.

The wiki page about porting valgrind contains many hints about how to
proceed. I'd add the following:

* Read http://www.gnu.org/software/hurd/hacking-guide/
* Play with rpctrace and read its source (hurd/utils/rpctrace.c)

I think (but please correct me if I'm wrong here) that valgrind on
Hurd would have to do the same thing as rpctrace (i.e. intercepting
and parsing messages from the target program) so it would be nice to
move this code to a library (modulo the stuff that is printing the
messages) so it can be reused.
