Early exit techniques

[pjaquiery]

I currently throw in JScript to initiate an early exit from a build. This results in the Failure Steps being executed. If I set a macro in the throw process I can test it in the Failure Steps processing and do appropriate stuff (or nothing). However, this is somewhat cumbersome. Is it possible to either perform the equivelent of a catch in the Failure Steps processing (so that the thrown object can be tested), or in some future version provide an Abort or Exit step that allows either a clean exit or a way (set a macro?) of signaling the Failure Steps processing?
