	Quick sidenote: the project noted above from sourceforge.net is dated and a bit flawed. Please use the version from ltp: https://github.com/linux-test-project/ltp/tree/master/testcases/open_posix_testsuite — if you have any questions or concerns, please feel free to contact me directly (yaneurabeya@ on github, etc). I’ll do my best to push through compatibility improvements where it makes sense.
