>          Issue Type: Bug
>          Components: proton-c

>            Assignee: Cliff Jansen
>            Priority: Major
>
> The normal cleanup procedure for epoll and win_iocp proactors waits for all 
> async activity to complete before freeing memory.
> pn_proactor_disconnect can't actually force a close so it launches a separate 
> async activity piggy-backed on the internal wake mechanism of any connections 
> to be closed.
> If the disconnect is happening at the same time as a separate thread doing a 
> normal close, a new wake can result after concluding there are none left.
> The solution is to mark the connection as "already awake" before entering the 
> cleanup code so new wakes are no-ops.  The libuv proactor doesn't need this 
> as the disconnect function is managed within libuv and never competes with 
> the normal close operation.
