[Mono-winforms-list] Handle being created when I don't expect

[Maser, Dan]

   That's the first time the HandleCreated event is fired, I have a MessageBox.Show in the first line of the HandleCreated handler and this is the first time I see it.  As such, how can I show you a call stack for the first time the handle is created if this is the first time the HandleCreated event is fired?

   I wonder if I should hack in some Console.WriteLine statements into the mono source and recompile to see?

When setting MdiParent the handle is being *re*created, not created, and this is matching MS' behavior.

To know when the handle was created in the first place I'd need another stack trace :)
