[Mono-list] mono-fastcgi-server on 64-bit os?

I'm slowly getting a bit further with the whole mono webserver thing, but
I've hit another snag.

I'm tracked the problem to xsp-2.10/src/Mono.WebServer.FastCgi/Record.cs:

    internal static ushort ReadUInt16 (byte [] array,
                                       int arrayIndex)
      ushort value = array [arrayIndex];
      value = (ushort) (value << 8);
      value += array [arrayIndex + 1];
      return value;

This function is returning really odd values, specifically breaking this and
forcing it to hang when this code is run:

    private static void ReceiveAll (Socket socket, byte [] data, int length)
      if (length <= 0)

      int total = 0;
      while (total < length) {
        total += socket.Receive (data, total,
          length - total,

Since the request length read is read using ReadUInt16, and the value coming
out of that is about a thousand times larger than the actual body length, it
hangs on socket.Receive; which in turn causes xsp4 to throw a code 500
because (as far as I can tell) thats what it does the fastcgi server times

I've seen a few posts about using MemoryStream and BinaryReader to do a
ReadUInt16 that works correctly, but my lame attempts to patch the code and
make it work were entirely unsuccessful (and to be honest I'm not even sure
why it's not working; should the << 8 be << 16 for 64 bit?)

Can anyone point me in the right direction here?
