 ----
-    For PHP 5.0.0:
     * Allow foreach ($array as $k => list($a, $b)) syntax for multi
       dimensional arrays.
     * Look at replacing c-lib call tolower().
     * Make hash API functions work with HASH_OF() to save time.
     * Allow to set a default value for call-by-reference-parameters. 
       eg: function hello (&$pallo = NULL) {} 
-    * Disallow function(method) redefinition in class.
     * Add configure test to determine if dlsym() requires underscore and set
       DLSYM_NEEDS_UNDERSCORE accordingly. Perl and zsh have it in configure, 
       for example. (DONE?)

     * Make sure that all ZTS globals get destructed. Most ts_allocate_id()

+    * provide optional IPv6 support (seems to be done?).
     * find a better way to implement script timeouts. SIGVTALRM is used
       by some POSIX threads implementations (i.e. OpenBSD) and is not
       available in ZTS mode.
     * Implement flush feature suitable for nested output buffers.
 
+Streams
+-------
+    * Route filestat.c through the wrapper layer; isolate the statcache code
+	  so that it is independent of php functions and can be applied to any
+	  stream/path.
+    * Add unlink() operation to wrappers, route userland unlink() through it.
+      Implement unlink() operation for the ftp wrapper.	  
+	* Add a method to take ownership of the memory buffer in memory streams so
+	  that generating string values for zvals doesn't require an estrdup.
