Perhaps there's a leak in the WinPcap implementation of 
pcap_findalldevs().  I didn't see any immediately obvious one.

Polling might be overkill for that.  At least in NT 5.x (W2K, WXP, 
etc.), you might be able to use RegisterDeviceNotification():

to get events delivered to a window when new devices are added or removed.
