I am understanding as below,
_this() increments the ref counter with omniORB2.8.
but _this() doesn't increment the ref counter with omniORB3.
The reason why I am understanding like this is that
I checked the value of "myecho->pd_refCount" before and after 
"myecho->_this()" , then the value was not changed.
Is it right ?

If _this() doesn't change the ref counter,
it seems to me that both Echo_var and POA refer to a servant 
after _remove_ref() is called.
Am I misunderstanding ?
