Perhaps also make some basic checks, such as binfo.avail_cpus <=
binfo.max_cpus.
ok

Here you can probably check that the min_* values is smaller than e.g.
1000, to catch randomly-filled values.
ok
Also, it would be useful to compile the tests with
-ftrivial-auto-var-init=pattern so as to fill the structures with random
values before making the gnumach calls.
good idea, I didn't know this feature.
