Okay, so using that logic we should head over to the os module and remove:
ctermid, getenv, getegid, geteuid, getgid, getgrouplist, getgroups, getpgid, getpgrp, getpriority, PRIO_PROCESS,
PRIO_PGRP, PRIO_USER, getresuid, getresgid, getuid, initgroups, putenv, setegid, seteuid, setgid, setgroups,
setpriority, setregid, setrusgid, setresuid, setreuid, getsid, setsid, setuid, unsetenv, fchmod, fchown, fdatasync,
fpathconf, fstatvfs, ftruncate, lockf, F_LOCK, F_TLOCK, F_ULOCK, F_TEST, O_DSYNC, O_RSYNC, O_SYNC, O_NDELAY, O_NONBLOCK,
O_NOCTTY, O_SHLOCK, O_EXLOCK, O_CLOEXEC, O_BINARY, O_NOINHERIT, O_SHORT_LIVED, O_TEMPORARY, O_RANDOM, O_SEQUENTIAL,
Okay, I'm tired of typing, but that list is not even half-way through the os page, and those are all methods or
attributes that are not available on either Windows or Unix or some flavors of Unix.
Oh, and all those upper-case attributes? Yup, documented. And when we don't document it ourselves we often refer
readers to their system documentation because Python does not, in fact, return exactly the same results on all platforms
-- particularly when calling into the OS.
