Is there a way to make bash job control quiet?

Bash is quite verbose when running jobs in the background:

$ echo toto&
toto
[1] 15922
[1]+  Done                    echo toto

Since I'm trying to run jobs in parallel and use the output, I'd like to find a way to silence bash. Is there a way to remove this superfluous output?

You can use parentheses to run a background command in a subshell, and that will silence the job control messages. For example:

(sleep 10 & )
