I'll have to remember that feature, but unfortunately it's new in bash 
4.1, so unless we're giving up 3.2 as the minimum for the tree....

        : $(( ++mj_num_jobs ))

Any reason not to do just

        (( ++mj_num_jobs ))

?

        : $(( --mj_num_jobs ))

                : $(( ret |= $? ))

Same.
