But on top of what Walter has said:

- Is it even guaranteed that the WNDPROC will be called only in the 
program's own call stack?

- Just looking at how SendMessage works across threads, can we rely on 
it to properly notify the calling thread that the message has been 
processed if the WNDPROC throws?

- Chances are you'll want to avoid just letting exceptions abort the 
entire program.
