Note:
even though poll() (as opposed to ppoll()) only accepts milliseconds
as userspace interface, the behavior will still improve because the current
time no longer needs to be rounded up to the next jiffie, so on average
a 500 microseconds behavior improvement.
Another way to get down in the timeout resolution for newer kernels, and
still supporting the syscalls with millisec timeouts, is to use timerfds.
