I meant that they may dispatch on something like cpuid to adjust to the
architecture at runtime, and presumably maintain the state for the
architecture on which they start. I guess you could get the same sort
of thing for dynamic compilation ("JIT"?).

How do you access the list of granted resources (as apposed to requested
ones)? I thought that needed (a free) implementation, which I want for
other reasons.
