Review comment:
Hello @miklosgergely. The current change wait for 100ms whereas I have
changed this to wait until 10s. I'm not sure what the value is of setting a
timeout, it will always just loop again. Since I do not see any value here,
but I wouldn't want to remove this as part of this ticket, I simply increased
it. Logging once every 100ms would be far too verbose. So you see, this change
is logging-related. :)
