Comment(by lala):

 Yes, after a while events/0 stops eating CPU.

 Somewhere between 11-19 hours after boot events/0 raised in (h)top.
 Between 30-35 hours uptime dropped to 0-0.6 %CPU. Somewhere between 48-53
 hours uptime raised again in "pole position". It's seems that is changing
 its state every ~17 hours.
