Description:
------------
Whenever i try to fetch a file from my server using http 1.1 PHP takes multiple seconds to load the file. The server is fine. Firefox and curl load it at no time.

i noticed the same behaviour under PHP 5.2.10 (code a bit different as the stream_context_set_default is new. But the result is the same.

When i fetch a bigger file i see readfile() hanging somewhere at 90% of the file but i guess depends on the file ;)

Reproduce code:
---------------
<?php
$default_opts = array(
  'http'=>array(
      'method'=>"GET",
      "protocol_version"=>1.1,
    )
  );

$default = stream_context_set_default($default_opts);
$start=microtime(true);
readfile("http://minsk/~mop/x");
var_dump(microtime(true)-$start);


Expected result:
----------------
Time needed should be <0.01s

Actual result:
--------------
mop@minsk:~$ time curl http://minsk/~mop/x

Size doesn't matter it seems. It always hangs!
