non zero exit codes for classes scripts

[Martin Krämer]

Hi Thomas,

Thanks for your Investigation.
Yes - I was not able to find any related changes, too.

Unfortunately as you already expected task_error does not end the full process tree - only fai-class.
Never the less it helped me to find a good workaround which I use as follows:

>&2 echo "error: my critical message"
(kill -9 $PPID &)
task_error 123

Kind Regards

Martin Krämer
