The previous test assumed that we could always rely on the minor fault
counter to change between reads of /proc/self/stat, but we found that
this is not the case.
The new test compares two reads of /proc/self/environ for which we have
set the same environment variable to two different values.
If the comparison shows the two reads have the same contents, we know
that /proc is not working.
I would like to thank Robin Johnson and Mike Frysinger for their input
for this patch.
