I'm working on working set issues right now. It should be better soon.
Will look at this one especially.

Thanks,
Tomas

Hi Aaron,
Sorry I wasn't trying to suggest a solution for your problem.  I was just
trying to narrow down where the increase in memory is coming from.
I suspect that the cause is initializing or calling into the core libraries
but I can't isolate that bit.

Hi Pete,

If I take the Execute method out of the loop then I don't get any
significant increase in memory usage. However as per my post above I
think I do need the CreateScope and Execute calls in the loop to allow
for multiple simultaneous script executions.
