(From my comment at BernardPHP)
Declare tick should maybe not be used at all, many places on the web it is suggested to use pcntl_signal_dispatch instead.
Inside the drivers, instead of usleep(), could use time_nanosleep, which is interruptable.

pcntl_signal_dispatch();
$nano = time_nanosleep(0, 100000000);
if ($nano === true) {
  // slept
} elseif ($nano === false) {
  // nanosleep fail
  usleep(100000);
} elseif (is_array($nano)) {
  // Interrupted by a signal
  pcntl_signal_dispatch();
  return array(null, null);
}
pcntl_signal_dispatch();

Hi @GDmac , thanks for letting me know about that! ✨

I'll update with pcntl_signal_dispatch according to your comment. Please let me know if you would like to address the improvement.

Nice, however beware,
you have not added the fail-safe,
in case nano-sleep returns false ?
