I'm not sure Danny is using it in the same way but
I first came across the term thunk in the Win32 API.
Microsoft used thunks to bridge between the new Win32 API
and the older 16 bit Win 3 API.

Why 'thunk' I do not know but the term seems to have stuck long
after everyone stopped using Win32 thunks...
