I suggest changing the description of posix_times() from "Get process times" to "Get current process times" in order to follow the "current process" naming convention of the other functions.This module contains an interface to those functions defined in the IEEE 1003.1 (POSIX.1) standards document which are not accessible through other means.
Sensitive data can be retrieved with the POSIX functions, e.g. posix_getpwnam() and friends.
Note: This extension is not available on Windows platforms.
