Unless you're running DNS on one of these boxes make that netstat -rn.
That's why it takes so long.  You're waiting for the DNS lookups to
timeout/fail.  Hmmm... maybe your /etc/hosts file is missing some entries
for your test setup?

Hmmm... which one is supposed to be x.x.x.3?  What do the *'s mean?  (Do
the *'s go away if you do -rn instead of just -r?)

On the BSD side at least there should be an entry which points traffic
intended for the box's own self to the localhost gateway.  Assuming
10.0.0.2 is the BSD box, I would expect a minimum table to look like:
Destination   Gateway            Flags     Refs     Use    Mtu   Interface
default       10.0.0.3           UGS         1        2     -    ppp0
10.0.0.2      127.0.0.1          UGHS        1       10     -    lo0
127.0.0.1     127.0.0.1          UH          1       24     -    lo0
