That is truly awful! Why wouldn't people just wrap in a runtime
exception ???? Truly, truly awful. :(
If we had to we could special-case for currentThread. :(

I would dispute that it can work "reasonably well in practice" given the
near impossibility of writing async-exception-safe non-trivial Java
code. That aside, the proposal is only for the stop(throwable) form
which I would not expect to be used for the termination case.
