[lldb-dev] lldb.frame.EvaluateExpression slows down when called a lot

[Scott Knight]

I attached the instruments trace here in case it might be helpful. Seems
like a lot of time is spent in the ClusterManager. It seems like thats
called from all the ValueObject. I do realize that I'm getting values over
and over again in a loop, but it seems to just take longer each time
through the loop. I also attached the python script I'm using in the zip
file as well.
