I just confirmed this in the IRC channel but figured Day of Testing etiquette 
requires an email to the proper list. 

Environment Detail:
        Single XCP 1.5 beta upgraded to XCP 1.6 build 61002c
                0 VMs in any state
        XenCenter 6.0.2 (Build 53158)

Symptoms:    CPU utilization on the host increased to 50% (dual core single 
                100% usage reported by xapi
Cause:    According to mcclurmc in the IRC channel this is a "known" bug in 
xapi's events system, where when xencenter is connected, xapi reports all 
events ever, instead of just the ones since next time"
