[IronPython] Some Objects not visible in my Shell?

[Curt Hagenlocher]

System.Threading is actually in mscorlib, so you'd have to
AddReference("mscorlib") as well. Alternatively, you can load both mscorlib
and System.dll in your hosting code by saying something like this:

ScriptDomainManager.CurrentManager.LoadAssembly(typeof(string).Assembly);
//mscorlib.dll
ScriptDomainManager.CurrentManager.LoadAssembly(typeof(System.Diagnostics.Debug).Assembly);
//System.dll

I think we've changed this in 2.6A1 so that these are always loaded by
default in hosting scenarios.
