small memory leak in simulation

[jerome]

when a simulation is launched a memory leak occurs : for ex1.xml (ubo/exercise), there is 400k loss for each launched.

This is not a huge loss, but it depends on the simulation time...

I think the loss come from :

• the call framework (small part 80K for ex1.xml project)
• the call to Do_Election->Check_Resource (between 0 and 4K but Do_Election is called in a loop depending on simulation time).

in last svn revision (1883), there is still a memory increase (> 1 mo) even if i clear the workspace. I join the file in the ticket.
