Description:
------------
This bug is very specific to Windows.  When executing a generic file upload 
using PHP, if at anytime while the file is being uploaded Apache then runs a 
CGI script like PERL or a C program, and the upload ends while the CGI script 
is still running, the uploaded file(s) in the temp directory will remain behind 
forever.

In order to avoid this the “php_do_open_temporary_file” routine will have 
to not use the “VCWD_OPEN_MODE” routine to open the temp file.  A generic 
Windows “open” call allows child processes to inherit their handles.  The 
temp file would need to be opened with a “CreateFile” call to open the file 
and specify the pSecurityAttributes option with bInheritHandle set to FALSE so 
that a child process will not inherit the open file handle.  The rub is this 
call uses a non-compatible handle so everyone who uses this handle has to be 
modified as well.



Test script:
---------------
Write or use any simple PHP upload program.  Next use CGI program below -- it 
doesn't need to do anything except take time.  So start the PHP upload, then 
start the CGI program below from a webpage.  Make sure the PHP upload completes 
before the script ends.


#include <windows.h>

void main(){
  Sleep(2*60*1000);     // sleep 2 minutes
}

Expected result:
----------------
The file should be uploaded and the temp file in the temp directory should not 
be present when done.  It should be moved to the destination directory.

Actual result:
--------------
The temp file remains forever in the temp directory, though the file is copied 
correctly to the destination directory.
