Why do I end up in RtlQueryInformationActivationContext?

I’m trying to debug a performance problem, and a significant
amount of my time is spent in RtlQueryInformationActivationContext.
Unfortunately, there’s no information on this function, whatsoever,
on the web, on osr.com, on MSDN, in the DDK, or elsewhere.

What is it, why is it eating my CPU, and where can I go to find
out what to do about it?

Cheers,
