>    Affects Versions: 1.6
>            Reporter: Alexei Scherbakov

>
> Currently exchange futures share same queue for pending(incomplete) and completed exchanges.
> The queue has fixed hardcoded size of 1000.
> This leads to a problem when > 1000 nodes try to enter grid.
> In such case oldest exchanges will be removed by ExchangeFutureSet size limit, leading
to whole exchange hanging.
> Solution: 
> 1. Use separate queues for pending and completed exchanges.
> 2. Pending exchange queue must be unbounded.
> 3. Add system property to control exchange history.
