Is that similar to what user-mode linux does? I mean the principle.

You still intersect *each* syscall, why not to do the same for
and replace events with correct value? Seems you do something similar
in a vu_wrap_poll.c: wo_epoll_wait(), right?

Don't get me wrong, I really want to understand whether everything
looks so bad without proposed change. It seems not, because the whole
is based on intersection of each syscall, thus one more one less - it
does not
become more clean and especially does not look like a generic purpose
which you seek. I may be wrong.
