Try running the test from a cron job without regrtest (i.e. ./python
Lib/test/test_posix.py), and putting some extra prints in it.

Some of the functions tested (e.g. ctermid, getlogin) use stdin to
determine who is logged in.  Maybe these should just be ignored if
they fail with this specific error (since the error means they're
working as advertised).

This one I don't understand.  Maybe the sleep(1) in the test isn't
long enough?
