commit 0897c551c0a098020f145885de06a5c10e5cc96b
Author: Carlos O'Donell <carlos@systemhalted.org>
Date:   Wed Jan 21 10:08:18 2015 -0500

    tst-getpw: Rewrite.
    
    The test is rewritten to look for the testable conditions and
    exit once they are all detected. This prevents the test from
    iterating over 2000 UIDs and looking up each one. It speeds up
    the test and prevents it from failing if the system under test
    has an NSS-based passwd that is slower than the test timeout.
