Description (last modified by cneumuel)
When many algorithms are executed in parallel some fail because the ExecutionContext property of Parameters and Operators is null. It is unclear why ExecutionContext can be null (it might be related with #1522).
This issue was found on a 4-core machine.

adds SetControl to IStatefultem to check which object cleans it up.

tickets.
r6495 checked in test-case for this issue.
The following output shows the number of instances each genetic algorithm consists of. It shows that there is an issue with the objects used in the genetic algorithm instances (the number of objects increases before cleanup).
(before cleanup and after cleanup are inserted for debugging purposes in Algorithm.OnStopped right before and after ClearState is called on the IStatefulItems)
