there is no single POSIX -- what version are talking about
The current version, POSIX.1-2013. The code also works in POSIX.1-2004. At this point older POSIX releases are mostly just historical curiosities; application developers shouldn't need to worry about them.

No, I didn't mess with the caches. I'm reasonably sure everything was cached.
