It could be usefull if the instruction pointer/return address that was

This would assume:
1. To be interrupted processor pushed it's own instruction pointer onto
the stack.
2. To be interrupted processor pops it's own instruction pointer from
stack.

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.

Skybuck.
