in thread Sleep has high cpu

Some time ago I needed to have that kind of spinning (scanning large number of connections on a chat room for activity) but under low load, in the middle of the night, the same code killed the machine.

I found using Time::HiRes to put a micro sleep inversely proportional to the number of active connections stopped the process from spinning out of control and allowed the OS to pre-empt the loop.

Thanks
