_Exit() function

Hmm, I disagree.

The manual pages are the system reference and therefore should neutrally 
document the system, regardless of the feature's obscurity, 
deprecatedness or non-portability (which can in turn be documented, of 
course).

It might be irrelevant but the manual is not the place where this line 
should be drawn. In the ideal world, all stuff would be added or removed 
along with its documentation.

If it's in libc (as is the case with _Exit()), it certainly should be 
mentioned in a manual page.

My 2¢,
Sascha
