Description:
------------
The engine seems to register old-style-ctors twice, once 
during parent-ctor-inheriting and once during 
normal-method-inheriting 

Reproduce code:
---------------
<?php
class foo {
    public function foo() {}
}

class bar extends foo {
}


ReflectionClass::export("bar");


Expected result:
----------------
  - Methods [1] {
    Method [ <user, inherits foo, ctor> public method 
foo ] {
      @@ /usr/src/php/5.2/bug.php 3 - 3
    }

Actual result:
--------------
  - Methods [2] {
    Method [ <user, inherits foo, ctor> public method 
foo ] {
      @@ /usr/src/php/5.2/bug.php 3 - 3
    }

    Method [ <user, inherits foo, ctor> public method 
foo ] {
      @@ /usr/src/php/5.2/bug.php 3 - 3
    }
