>          Issue Type: Bug
>          Components: Container
>    Affects Versions: 1.2.0
>            Reporter: Alan Conway
>            Assignee: Alan Conway
>            Priority: Major

> The attached reproducers link-leak.c and link-leak.py open and close links repeatedly
on the same connection. This causes the routers memory use to grow.
> Massif shows that the memory is due to pn_link_t and related objects. PROTON-905 describes
an old bug where link information is leaked but experiments show this is not happening with
modern proton.
> I suspect the growth is due to dispatch sometimes failing to call pn_link_free() but
investigation is still ongoing.
