Yeah, that's exactly the implementation I'm asking for (and perhaps we can add 
it to libkdefakes). I *have* such an implementation from FreeBSD, but it's 
licensed incompatibly. Hence my request for someone to pull it out of glibc 
(if LGPL) or otherwise I'll have to, um, close my eyes and do a clean room 
implementation of it or something :)
