How to Abort Data Services Job Programatically ?

[#1]

We have a Data Services job that "hangs" now and then, and never ends. In SQL Table  "AL_HISTORY" the column  "END_TIME" is NULL.

Is there a way I can programmatically identify this "hung" job, and create a process to automatically abort it, without a user having to abort it manually ?

PS. Is there a better place to post this question ? This was the best I could find.
