[Bug 28290] New: shell32/shelllink.ok test flaky

http://bugs.winehq.org/show_bug.cgi?id=28290

Summary: shell32/shelllink.ok test flaky
           Product: Wine
           Version: 1.3.27
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: shell32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When running with WINEDEBUG=warn+heap (on my 32 bit i7 natty box
running in low power mode, fwiw), twice I've hit the error

../../../tools/runtest -q -P wine -M shell32.dll -T ../../.. -p
shell32_test.exe.so shelllink.c && touch shelllink.ok
shelllink.c:728: Test failed: save failed (0x80070020)
shelllink.c:728: Test failed: got 0x00000001
shelllink.c:728: Test failed: Didn't expect NULL
shelllink.c:474: Test failed: GetCurFile fails on shell32 < 5.0
shelllink.c:732: Test failed: GetDescription returned 'command on path' instead
of 'command on path without .exe'

This test keeps overwriting the same file with new data, iirc.
The previous thing it wrote was "command on path", so it looks
like the immediately previous testcase sometimes leaves a reference dangling?
I think 0x80070020 is "sharing violation".
