problem with sockets under win32; premature connection termination

[Downs]

The following code should theoretically wait for a single TCP connection, and transfer a file over it.

import std.stdio, std.socket, std.string, std.file;

void main(char[][] args) {
  auto l=new Socket(AddressFamily.INET, SocketType.STREAM, ProtocolType.TCP);
  l.blocking=true;
  with (l) {
   bind(new InternetAddress("0.0.0.0", atoi(args[1])));
   listen(16);
  }
  auto request=l.accept;
  request.send("HTTP/1.0 200 OK\r\n\r\n");
  request.send(read(args[2]));
  request.shutdown(SocketShutdown.BOTH);
  request.close;
}

Trying to use this program to host a file (images work best), I ran into the following problem:
the image would transmit, partially, then the request.send call would return - prematurely -
and the rest of the unsent data would be silently discarded.
Experimenting with linger and SetOption produced no discernible effect.
I've tried to find a solution to this problem for weeks now, but I don't seem to be making headway.

Halp? ;_;

PS: If you try to replicate it, it is recommended to use a mid-latency connection so that the transfer doesn't complete immediately.
PPS: Interestingly, it works with netcat. Firefox, IE and Opera break though.
