It would be an unusual machine where you couldn't modify the return
address on the stack to change the address you return to.

This does make me wonder how Windows 7 terminates threads/processes/hanging 
applications.

Apperently there is some kind of mechanism for this.

Perhaps it's not fully exposed to application developers or perhaps in a 
somewhat more complex way via all kinds of APIs ?

An example of how to terminate threads/processes instantly on Windows 7 
could be interesting.
