I don't get this: Why implement module loading just for this? Can't
SystemTap be just statically linked in gnumach? Or are the actual test
functions compiled and loaded as modules in SystemTap?...
In the latter case, I agree that it would be a bit ugly. It may still be
the preferable solution though, if the other option of running it is
user space involves much more effort and/or risk...
