These rt* daemons are related to real time audio setups.

rtirq by Rui Nuno Capela [1] is a startup script for realtime-preempt
enabled kernels which allows to make use of the threaded IRQs as used by
real-time kernels or kernels >= 2.6.39 with the threadirqs kernel option
enabled. It is used in some realtime audio setups, so I guess there are
people interested that the rtirq script also works with runit.

rt-hwtimers, rt-pcilatency, rt-swtimers (see code below) are startup
script I wrote as optimizations for my RT DAW (Real Time Digital Audio
Workstation) setup ... So I think you can remove them from the list.

If it can be of interest for someone here is the code:

~~~
