Sample app that demonstrates the problem

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.13)
Gecko/20101206 Ubuntu/10.10 (maverick) Firefox/3.5

DataGridViewColumns that are added to a DataGridView aren't disposed when
calling DataGridView.Dispose().

This is bad if the column holds unmanaged resources that need to be released or
otherwise the app hangs.



Reproducible: Always

Steps to Reproduce:
Build and run attached sample.
Actual Results:  
Output of sample app when run on command line:
Undisposed MyDataGridViewTextColumn objects: 1


Expected Results:  
Undisposed MyDataGridViewTextColumn objects: 0
