This is a pretty cool series, but I'm left wondering "for what reason?" :) Perhaps I missed the specific rationale; there was a lot to run. ;)
It would be useful, sure, but is there something that does, in fact, need this, or would like this if it were available? Since this provides a userspace API, what would be consuming that API? For example, when Syscall User Dispatch was added, it was clear it was for Wine[1].
