Yes, we can, and I'm happy to follow up with that as part of my TIF
clean up work, but can we not block the current patchset to be merged

submission?

In that case, I'd say just add the new TIF flag. The consolidation can
come later.

No. This is exactly the wrong order. Cleanup and consolidation have
precedence over features. I'm tired of 'we'll do that later' songs,
simply because in the very end I'm going to be the idiot who mops up the
resulting mess.

No problem.  I will follow up with a patchset consolidating those flags
into this syscall_intercept interface I proposed.  I assume there is no
immediate concerns with the consolidation approach itself.
