Timing problem somewhere? Maybe an even closer look at your work, 
combined with tcpdump, will reveal the mising pieces.
But if you do traceroute on the inet, you'll often see *'s; it's not 
exactly uncommom. Your 29ms or so might seem a bit longish on a small 
internal network. OTOH, postings seems to to indicate quite a lot are 
having routing/bridging problems with Xen, so...
