msg/async/Timeout: always round up
Currently, we always round down, which has a bad side effect: when a
timer comes closer, we have lots of early wakeups, and eventually
we'll run into a busy loop (timeout=0) when the timeout is less than
one millisecond; the process will remain this busy loop for one
millisecond, wasting lots of CPU time.
