--- Comment #2 from François Gouget fgouget@codeweavers.com --- A couple of other failures also happen even less frequently:
process.c:1209: Test failed: OpenProcess failed 5 process.c:1224: Test failed: OpenThread failed 5
These happen when the process we identified through its ppid happens to be a privileged system process.
