GNU Parallel Bug Reports parallel/--halt-on-error

[Brian Ericson]

Given:
       --halt-on-error val
       --halt val
                How should GNU parallel terminate if one of more jobs fail?

                0      Do not halt if a job fails. Exit status will be 
the number of jobs failed. This is the default.

                1      Do not start new jobs if a job fails, but 
complete the running jobs including cleanup. The exit status will be the 
exit status from the last failing job.

                2      Kill off all jobs immediately and exit without 
cleanup. The exit status will be the exit status from the failing job.

                1-99%  If val% of the jobs fail and minimum 3: Do not 
start new jobs, but complete the running jobs including cleanup. The 
exit status will be the exit status from the last failing job.

And:

$ ls

$ parallel --no-notice -j100 --halt-on-error 2 'sleep {} && touch {} && 
exit 1' ::: 2 4 8; ps -ef | grep [t]ouch; ls; sleep 8; ls
parallel: This job failed:
sleep 2 && touch 2 && exit 1
bme       6621     1  0 15:12 pts/1    00:00:00 /usr/bin/bash -c sleep 4 
&& touch 4 && exit 1
bme       6623     1  0 15:12 pts/1    00:00:00 /usr/bin/bash -c sleep 8 
&& touch 8 && exit 1
2
2  4  8

Shouldn't parallel stop the moment the first operation exits with a 1 
status (as reported)?
