Not really, the sub-text I mentioned is just one of those kernel
things that you 'just know' ;-). The problem is that people aren't
born knowing it.
Mostly in IOKit you don't have to worry about interrupt time as aside
from Filters you never run at interrupt time, which is how this hole
in the documentation came about.

call it at hardware interrupt time, or in IOKit terms at Filter time.
Does this help?
Sure ... but I don't see the sub text that you mention in the docs
I'm looking at, maybe there's a better source for documentation ...
