UTRACE_STOP in exec handler

Roland, I'm seeing a problem on with the new utrace on 2.6.27-0.323.rc6.fc10.x86_64. Basically, if I attach a new engine in an exec handler, and use utrace_control() with UTRACE_STOP, the task doesn't reliably stop. I was seeing this behaviour with systemtap, so I started with crash-suspend.c

Off hand I don't see anything wrong with your test module. But I'll have to test it out myself, and I won't be able to do that until I'm back from travelling (next week). Thanks, Roland
