hi, immm baack (sorta).

this actually seems to be what we (netbsd) would prefer, 
after reading the sysconf man page.

theorhetically this is doable now, it just has to be 
implemented.

So, after further review, it looks like the PR has
morphed into 2 issues really:

1) bad error reporting

2) using sysconf for posix compliance

now, for item 1, ive no idea what to do, for item 2
well that is sort of a can of worms because there are
a lot of things that do not route through sysconf
since sysctl is better.

recall our statement of "posix within reason".

i am sure we could do it, question is, do we
want to?
