To be strict, this is not POSIX standard. Therefore such check does
not guarantee procfs presence. And vice versa: procfs presence does
not require POSIX compliance. So, I'm not sure if such check is
correct. Better look at the sources.

And, AFAIK, POSIX does not cover process table info at all. So, on
Linux this is the only way. IMHO.
