Summary: urlmon/tests/protocol.ok slightly flaky:
                    protocol.c:2892: Test failed: ref=2
           Product: Wine
           Version: 1.3.27
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: urlmon
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I've seen this twice in two days:

../../../tools/runtest -q -P wine -M urlmon.dll -T ../../.. -p
urlmon_test.exe.so protocol.c && touch protocol.ok
...
protocol.c:979: Test failed: unexpected call ReportResult
protocol.c:984: Test failed: hrResult = 80004004, expected: 00000000
protocol.c:989: Test failed: dwError == ERROR_SUCCESS
protocol.c:2892: Test failed: ref=2
protocol.c:746: Test failed: unexpected call ReportProgress_CONNECTING

This time, it was with WINEDEBUG=warn+heap, on a system with:
os:     Ubuntu 10.04.3 LTS, 2.6.32-33-generic, pulseaudio
0.9.21-63-gd3efa-dirty, Advanced Linux Sound Architecture Driver Version
1.0.21.
ram:    3212 MB
cpu:    Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
gpu:    GeForce GT 240/PCI/SSE2 3.2.0 NVIDIA 195.36.24

I see a few vaguely similar problems on windows at
http://test.winehq.org/data/tests/urlmon:protocol.html
so perhaps these tests still need some love.
