... which is not surprising as it traced eth0 ;-) [10.0.1.15 is the IP of the box and routes back to loopback]
with the proper tcpdump it gave:
[root@europe ~]# tcpdump -i lo tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on lo, link-type EN10MB (Ethernet), capture size 96 bytes 16:15:05.260000 IP europe.37198 > europe.distcc: . ack 2022529163 win 257 <nop,nop,timestamp 209526 197526> 16:15:05.260000 IP europe.distcc > europe.37198: . ack 1 win 0 <nop,nop,timestamp 209526 7020>
hm, a window of 257 and zero, is that right?
