In between full polls, we do quick polls every 'pollinterval'  
(default: 2 seconds) to retrieve some info should the UPS not provide  
interrupt reports. Only NUT variables with the HU_FLAG_QUICK_POLL will  
be retrieved then, which typically means that we only need to refresh  
two or three reports (since status bits are usually aggregated in one  
or two reports), which limits the load to the UPS.

Setting the pollfreq to 5 seconds is counter productive here, since  
this will only increase the amount of reports to retrieve (which is  
something some UPS devices can't handle), while the things Justin is  
interested in will already be polled every 2 seconds anyway.

Best regards, Arjen
