[IronPython] Performance of dir

[Michael Foord]

Hello all,

On IronPython 2.0.1 the last line of this code takes ~4 seconds the 
first time it is executed:

 >>> import clr
 >>> clr.AddReference('System.Windows.Forms')
 >>> from System.Windows.Forms import *
 >>> dir(Form)

Form.__dict__.keys() (which for a .NET type is equivalent) takes ~1 
second or less. What extra work is dir doing? (Is it pulling in the xml 
docstrings?)

Thanks

Michael
