This is why we let asterisk setuid itself to user asterisk, and don't
let the wrappr script handle that. Asterisk sets scheduling priority
before running setuid/setgid .

It can help the quality of Audio. On the downside, it means that a 100%
CPU loop in asterisk is a pain to recover from. Security implications:
if someone can inject you one line to the dialpan, they can (under the
right circumstances) get your system stuck very badly . Unless you have
a manager connection availble.
