Yes I do.  Quite possibly the situation has changed since 2011, as the
rt patch is constantly evolving and being merged into vanilla..  I also
verified my results by asking the rt devs on IRC (not that this
constitutes proof), and a couple of them concurred that this would
indeed be good practice.

I'm sorry if it came across as a personal reproach, it was in no way
intended as such!  It was more of a general statement about linux
audio and the associated lore floating around on the nets, much of it
outdated or even untrue nowdays.  What I wanted to make clear is that I
was not simply repeating some advice found on the internet somewhere,
but rather based my comment on personal experience.
