[IronPython] Controling DLR/IronPython Memory Size

What version of IronPython are you using? Have you ngen'd the binaries?
Ngen will significantly reduce the amount of private working set IronPython
I assume you don't have a "site.py" or the standard library present or I
think it'd probably be more.
On my machine (some post-RC1 Windows 7 build) I see:
C# Hello World: 1.5MB Private working set
"ipy.exe -S" (IronPython 2.6B2, ngen'd binaries): 4.7MB private working set
Giving us about 3.2MB to start up IronPython including its REPL.
2.6 certainly is better from a working set perspective than 2.0 is but the
gains there are mainly for large applications.
2.6 should also see better WS on non-Vista platforms. This is because
we've fixed the base addresses up to make sure that ngen'd binaries don't
require being re-based when they get loaded.
We haven't really focused on memory usage of hello world at all. But we'd
welcome a bug on CodePlex to draw our attention to the problem.
