I actually started to see this when doing scans over a VPN (such as
OpenVPN). Nmap would never wait long enough for the ARP replies (or
they got dropped). Just trying it now on an iMac and very similar for
local network now.

Attempts to scan outside of the subnet are returned with:

nexthost: failed to determine to xx.xx.xx.xx

This is with both alpha4 AND alpha5.  Time is short right now but I'll
take a deeper look this evening.  I'm under the suspscion it's
somewhere in the ARP code when doing anything outside of a Connect()
scan.
