Hi all,

as we get closer to having the current tests all patched I want to have a place to post new "failures" - since the BOT process is unable to report regressions before all tests are passing for a time.

Initially, the tests run normally, and report two unexpected failures. However, the second pass does not complete - it is giving a segmentation error (repeated twice, starting third run shortly).

i.e., the tests test_eintr and test_importlib have PR that are waitig to be merged. the failure of test_os and test_xml_etree_c are new.

Well, I can close this again - whatever was wrong with test_xml_etree_c disappeared - and a cursory look at test_os reveals that the issue might be the time lag between the NFS server where the temp files are made and the "local" sense of time.

Most of the time I do not have an issue, so closing as false positives.
