I find that IOCP was added in 0.9.39.

HANDLE WINAPI CreateIoCompletionPort(HANDLE hFileHandle, HANDLE
hExistingCompletionPort,
                                     ULONG_PTR CompletionKey, DWORD
dwNumberOfConcurrentThreads)
{
    NTSTATUS status;
    HANDLE ret = 0;

    TRACE("(%p, %p, %08lx, %08x)\n",
          hFileHandle, hExistingCompletionPort, CompletionKey,
dwNumberOfConcurrentThreads);

    if (hExistingCompletionPort && hFileHandle == INVALID_HANDLE_VALUE)
    {
        SetLastError( ERROR_INVALID_PARAMETER);
        return NULL;
    }

    if (hExistingCompletionPort)
        ret = hExistingCompletionPort;
    else
    {
        status = NtCreateIoCompletion( &ret, IO_COMPLETION_ALL_ACCESS, NULL,
dwNumberOfConcurrentThreads );
        if (status != STATUS_SUCCESS) goto fail;
    }

    if (hFileHandle != INVALID_HANDLE_VALUE)
    {
        FILE_COMPLETION_INFORMATION info;
        IO_STATUS_BLOCK iosb;

        info.CompletionPort = ret;
        info.CompletionKey = CompletionKey;
        status = NtSetInformationFile( hFileHandle, &iosb, &info, sizeof(info),
FileCompletionInformation );
        if (status != STATUS_SUCCESS) goto fail;
    }

    return ret;

fail:
    if (ret && !hExistingCompletionPort)
        CloseHandle( ret );
    SetLastError( RtlNtStatusToDosError(status) );
    return 0;
}
