Description:
------------
When using both curl and multi_curl i get a curl_errno of 0 for each handle while an curl_error results a string error.

When using multi_curl the error string is:  Failed connect to ftp.nmh.ac.uk:21; Operation now in progress

When using curl the error string is: couldn't connect to host

Using multi_curl results in a null body returned with curl_multi_getcontent
Using curl yields the data of the file when using curl_exec

Test script:
---------------
two scripts are below to reproduce.

# multi_curl method
<?php

$curls = array();
$cmh = curl_multi_init();

$dlFiles = array(
  'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1914/sod1914.wdc',
  'http://spc.igpp.ucla.edu/uclamag/ffi/lal/B99300_LAL.ffd',
  'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1922/hua1922.wdc',
  'http://vmo.igpp.ucla.edu/data1/Weygand/ProcessedSolarWindGSE/ACE/mag/2000/acemag200001.dat'
);

foreach ($dlFiles as $x => $file) {
  $curls[$x] = curl_init();
  curl_setopt($curls[$x], CURLOPT_URL, $file);
  curl_setopt($curls[$x], CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($curls[$x], CURLOPT_FOLLOWLOCATION, 1);
  curl_multi_add_handle($cmh, $curls[$x]);
}

$active = null;

do {
  $mrc = curl_multi_exec($cmh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
  if (curl_multi_select($cmh) != -1) {
    do {
	 $mrc = curl_multi_exec($cmh, $active);
    } while ($mrc == CURLM_CALL_MULTI_PERFORM);
  }
}

foreach ($dlFiles as $x => $file) {
  var_dump(substr(curl_multi_getcontent($curls[$x]), 0, 10), curl_errno($curls[$x]), curl_error($curls[$x]));
  curl_multi_remove_handle($cmh, $curls[$x]);
  curl_close($curls[$x]);
}

curl_multi_close($cmh);


?>

# curl method
<?php

$dlFiles = array(
  'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1914/sod1914.wdc',
  'http://spc.igpp.ucla.edu/uclamag/ffi/lal/B99300_LAL.ffd',
  'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1922/hua1922.wdc',
  'http://vmo.igpp.ucla.edu/data1/Weygand/ProcessedSolarWindGSE/ACE/mag/2000/acemag200001.dat'
);

foreach ($dlFiles as $x => $file) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $file);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

  var_dump(substr(curl_exec($ch), 0, 10), curl_errno($ch), curl_error($ch));

  curl_close($ch);
}

?>

Expected result:
----------------
no errors at all and multi_curl letting me get the contents of the curl.

Actual result:
--------------
multi_curl
