result in a leak of a SystemState and ClrModule which were being hung onto by
an event rooted in the app domain. So if you’re re-creating the engine
each time you might be seeing that. Also, now that I’ve mentioned events,
you might want to check your own C# code if you’re using events: It’s easy
to forget to unhook one and leak memory because the event handler stays alive
forever.<o:p></o:p></span></p>

it consumes 2M more, i dont have a clue why is this...Does this version of IP
