The Linux / NPTL behavior does not obey the POSIX requirements about thread schedulin Details are available at: http://nptl.bullopensource.org/Tests/results/report.php Browse: (TC2) 2xi686HT - RHAS4u2 Run 1,2,3 See: http://nptl.bullopensource.org/Tests/results/detailed.php?run_id=12&testcase_id=1923 http://nptl.bullopensource.org/Tests/results/detailed.php?run_id=12&testcase_id=1925 http://nptl.bullopensource.org/Tests/results/detailed.php?run_id=12&testcase_id=2464 Version-Release number of selected component (if applicable): Unmodified RHEL4u2 How reproducible: Always Steps to Reproduce: Use OPTS.

There is no guarantee about the scheduling in this implementation.
(In reply to comment #3) > There is no guarantee about the scheduling in this implementation. Therefore this *is* an issue, since POSIX has some requirements about scheduling, and NPTL claims to implement this standard. Where is the mistake?
