When using the test suite when a multi-threaded task is killed with the "kill"
command a backtrace is generated.  I can duplicate this every time with the
following command sequence:

(fhpd) load ../pkglibdir/funit-threads-looper
Loaded executable file: ../pkglibdir/funit-threads-looper
(fhpd) run
Attached to process 10410
starting/running with this command:
/home/rmoseley/frysk-git3/build/frysk-core/frysk/bindir/../pkglibdir/funit-threads-looper

Running process 10410
(fhpd) run
