Re: memory leak associated w/running any ecap adapter

I just received a request for the patch mentioned in this thread so I'm just
going to paste it here for all future users since it doesn't appear there
has been a new release which includes this.

Tell the host application when we no longer need virgin body
so that the host application can get rid of allocated resources and
possibly terminate the transaction.
