Comment (by simonmar):

 Can you reliably repeat this behaviour?

 I'm still highly dubious that this is something GHC is doing.  My guess is
 that your firewall software is misattributing this packet to GHC.  ARP
 packets are generated by the IP implementation when it needs to map an IP
 address to a hardware address; it looks like your machine is checking the
 hardware address of the router (assuming your PC is 192.168.1.100 and the
 router is 192.168.1.1).
