Bug description:  file operations make loads of lstat64() calls and making code ineffective

Description:
------------
$ strace php -r 'for ($i=0;$i<5;$i++) 
{$fp=fopen("/home/glen/tmp/php/long/test/dir/is/here/$i","w");fclose($fp);}'

2>&1 |grep /home

this will call lstat64() each time on:
/home
/home/glen
/home/glen/tmp
/home/glen/tmp/php
/home/glen/tmp/php/long
/home/glen/tmp/php/long/test
/home/glen/tmp/php/long/test/dir
/home/glen/tmp/php/long/test/dir/is
/home/glen/tmp/php/long/test/dir/is/here

while it should either don't do them at all or at least 
cache the paths that haven't been altered (i only write to 
last dir)
