Sorry to not clarify earlier - it doesn't, in fact. But for it to perform
well (eg. realtime multitrack recording, FX-ing and mixing, it needs to
have realtime scheduling. And this requires root privilege.

jackstart is a program that uses "capabilities" (still trying to figure
out how that is different to suid, and whether my kernel has it) to start
jackd with appropriate scheduling priority.

JACK = Jack Audio Connection Kit, for any interested
