* Memory manager stores a list of generated objects to control them.

* So container objects always have at least one reference and can't be automatically destroyed.
|
|

|
|
* This class is intended to be an userland proxy to memory container object.

|
|
* Class also provides Zend_Memory_Container_Interface interface and works as proxy for such cases.
