I don't understand...ReadFile with OVERLAPPED parameter doesn't modify the 
HANDLE's file position, so you should be able to mix read()/pread() however you 
like (as long as read() is only called from one thread).

I tried without ReOpenFile and it seems to work like a charm, or am I missing 

ssize_t mingw_pread(int fd, void *buf, size_t count, off64_t offset)
        DWORD bytes_read;
        OVERLAPPED overlapped;
        memset(&overlapped, 0, sizeof(overlapped));
        overlapped.Offset = (DWORD) offset;
        overlapped.OffsetHigh = (DWORD) (offset >> 32);

        if (!ReadFile((HANDLE) _get_osfhandle(fd), buf, count, &bytes_read,
            &overlapped)) {
                errno = err_win_to_posix(GetLastError());
                return -1;
        return (ssize_t) bytes_read;
