When the program child.c does an exec, there's no external indication that the exec occured; should modify the program so that it, via command line options, indicates the exec.
Index: frysk-core/prog/ChangeLog 2005-12-22 Andrew Cagney <cagney@redhat.com> * kill/child.c: Implement --filename=<program> argument. For execve, argv[0] to PID:TID, and pass through --filename=, --wait=. the value can be seen in /proc/PID/cmdline, but that isn't yet visible via frysk.
