The compat layer timeout handling changes in:
9f72949f67
are busted. This is most easily seen with an X application
that uses sub-second select/poll timeout such as emacs. You
hit a key and it takes a second or so before the app responds.
The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it
should instead be using {tv_usec,ts_nsec}, which perfectly explains
the observed incorrect behavior.
Another bug shot down with git bisect.
