Bug description: Not closing download handles

I tried to download file with curl, p it with external app, show
output and kill temp file. But:
1. if php as isapi module - when several requests at one time some inputs
are locked! Filemon says that it frees by some cmd.exe after all runned
sub-processes already finished. Very strange!
2. if php as fastcgi - it often crashes with error in php_curl (all latest
dlls in system32 upgraded; php4ts only in c:\php, php4isapi also in c:\php
and no in c:\windows\system)
3. if php as cgi - all OK, except of when user cancelled download the
script terminated, but shotdown_procedure not called, so temp files left.

Reproduce code:
<?ob_start(); $url="";
$oinfile = tempnam ("./", "URLIN");
$infile = preg_replace("#.*[/\\\\](.*?)#","\$1",$oinfile);
$ooutfile = tempnam ("./", "URLOU");
$outfile = preg_replace("#.*[/\\\\](.*?)#","\$1",$ooutfile);
"unlink(\"$infile\"); unlink(\"$outfile\"); unlink(\"$oinfile\");
unlink(\"$ooutfile\"); return 1;"));
$inf = fopen($infile, "w");
fwrite($inf, "<meta http-equiv=\"Content-Type\"
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_FILE, $inf);
$st=curl_exec ($ch);
curl_close ($ch);
echo `filter.exe $lang $infile $outfile 2>&1`;

Expected result:
No .tmp files not in windows\temp\ folder, not in script folder.

Actual result:
Some .tmp files left and in windows\temp, and in script folder.
