See RFC 1122 chapter 2.3.2.2 ARP Packet Queue:
"The link layer SHOULD save (rather than discard) at least
one (the latest) packet of each set of packets destined to
the same unresolved IP address, and transmit the saved
packet when the address has been resolved."

It might even be a good idea to drop our multiple-packet-queue and have a single-packet-queue instead, which would be enabled by default. The problem of lost packets also came up multiple times on lwip-users already.
