So is there a reason it's not being documented? I've got a 
deprecation message saying to switch from std.c.linux.linux to 
core.sys.posix.*

Generally I'd assume undocumented features mean "don't use this", 
or at least "use at your own risk" (I believe that's why 
deprecated features are removed from the docs before they're 
pulled from the code). It looks like doc comments are pretty 
sparse in core/sys - is that the only reason docs aren't being 
generated?
