    by  main (test.h:624)
Though, looking at the code, these warnings are caused by:
    ret = PdhCloseQuery( query );
    ok(ret == PDH_INVALID_HANDLE, "PdhCloseQuery failed 0x%08x\n", ret);
e.g., these invalid reads are expected.
Filing a bug so I have something to reference in the valgrind suppression file.
