OK, this is odd.  It looks like it's just ignoring the default route.  If I add
gateways of the form:

route add -net 0.0.0.0 netmask 128.0.0.0 gw 169.254.1.1
route add -net 128.0.0.0 netmask 128.0.0.0 gw 169.254.1.1

such that

route -n gives

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
207.210.101.187 0.0.0.0         255.255.255.255 UH    0      0        0 eth0
169.254.0.0      0.0.0.0         255.255.0.0     U     0      0        0 eth0
0.0.0.0         169.254.1.1      128.0.0.0       UG    0      0        0 eth0
128.0.0.0       169.254.1.1     128.0.0.0       UG    0      0        0 eth0
0.0.0.0         169.254.1.1     0.0.0.0         UG    0      0        0 eth0

then it uses the default gateway properly and doesn't arp for all the ips --
just 169.254.1.1

It does still arp for 169.254.1.1 (resulting in a slow arp reply response)

Sheesh.

BTW, arp is probably slow because it's being bombarded with requests.
