Bug #: 30762
           Summary: msxml3/domdoc tests flaky
           Product: Wine
           Version: 1.5.4
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: msxml3
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

ca48dac8821e128db8991dc54b4dedc8c321e816 and 
9c0486d7a802c2f618a56a2074c5d790d329e3cf
both seem to have introduced some flaky tests in msxml3/domdoc.  
Here's the result of 455 runs in a loop on ubuntu 12.04 (though I
also saw these on Centos 6):

342 domdoc.c:11537: Test failed: got L"http://blahblah.org"
    342 domdoc.c:11542: Test failed: got L"http://blah.org"
    350 domdoc.c:11647: Test failed: got L"http://blahblah.org"
    350 domdoc.c:11652: Test failed: got L"http://blah.org"
      3 domdoc.c:2098: Test failed: can't create file
