Your netmask for the ethernet interface does include the IP address of
the SLIP peer.  As long as the SLIP interface is up & running, its own
host route gets precedence over the ethernet network route.  However,
if the modem drops carrier, the specific host route (this is the
_remote_ IP address of the SLIP i/f) disappears, hence all further
packets for this address default to the ethernet route, and the IP
layers attempt to ARP for it on the ethernet.

Never trust an operating system you don't have sources for. ;-)
